Nitrome Bug Email Adress

The email icon on Nitrome's contact page

A glitch, also known as a bug, is a flaw in the programming of a game, causing it to work improperly. There are a number of Nitrome games with noticeable glitches, some which can prevent proper gameplay or players from passing certain levels. Nitrome's earlier games had more glitches than the rest, and glitches became rarer as Nitrome's game development got better. Due to Nitrome's current situation with them creating a new website, they appear to have stopped managing their old one and as a result, glitches are becoming more frequent in many of their games. If a player experiences a glitch, they can email Nitrome at the email address "". A list of glitches in games is listed below.


These glitches are outside of Nitrome games.

Game high scores

Final Ninja Zero

  • On Final Ninja Zero, If the player presses the back button on the high scores repeatedly many times, they may go back far enough to see the 101st score, 121st score, or even farther.

Main games

Bump Battle Royale

  • It is impossible to play the Enemy 585 arena in either Last Man Standing, Team Battle or Multiplayer Mode as when this stage is selected, the Mirror Image arena is played instead.
Level 1 BBR glitch

The invisible character glitch. Note that the player is nowhere to be seen.

  • In Campaign Mode, if the player chooses the blue or yellow robot and plays level one, the player will be invisible and cannot see their cursor but Blue can still be seen.

Bad Ice-Cream

  • Occasionally, when a player traps a troll, or blue cow, then breaks the ice barriers to let them free, the enemy might just stand there with a question mark over its head for the entire course of the level.
  • If the player goes to the place, where the enemy is about to land, they die.
  • If the last fruit in a stage is collected just when player gets hit by an enemy, the ice cream will melt, but the player can still proceed to the next level.


  • The player may be able to fire their laser and hear its sound even after the level ends.
  • If a piece of rock is too small, firing the laser at it will not cut it in half. Instead, the regular "cut line" will continue to stretch across the screen.
  • On one level, if Canary 214-LE shoots a laser at the black rock in the end room, his laser may cut the rock, the rock will show in the blackness (so the player can see it), and a white line will be seen where the player cuts.

Cave Chaos

  • Sometimes, the player can bypass through an enemy if the enemy falls on them.

Cave Chaos 2

  • An extremely common glitch happens when the player obtains the double jump power up. Whenever the player jumps, they will do a flip in the air, but they will not be able to jump a second time.
  • Sometimes if the player bumps a rock off the edge of a platform, and the bats places the next platform while it is falling, the rock will get caught in between the platforms and stay stuck there.

Chick Flick

  • On Level 3, small chicks may always fall through the thumper bumpers.
  • Sometimes chicks get stuck at the top of the screen and never fall. This happens with bombs sometimes too. This particularly happens with the tiny chicks.

Chisel 2

  • At the start of some levels, Chiseller may automatically win or lose.
  • When a level is automatically won, it will not be unlocked on the levels menu. The only way to unlock it is playing and passing the previous level and the level that is locked.
  • If Chiseller manages to destroy the entire planet they are on, Chiseller's drill sound may constantly loop and Chiseller will drill completely off the screen, freezing the level and forcing the player to quit.
  • On level 27, one Robearcop may fly off a planet to another planet, but not make it to the other planet, thus, the Robearcop will fly into space and off the screen.
  • On level 28, sometimes the entire planet will come together in a conglomerate blob, and reset how much the player has drilled.
  • On any planet if Chiseller stands on any part that is too thin then he will move left and right really fast causing the player to have to jump or reset the level.
  • Sometimes, drilling a planet will make part of the planet reappear that has already been drilled. Other times, part of the planet will disappear, often winning the level.
  • Sometimes when the player drills the planet to 100% the whole planet is drilled instead.
  • Chiseler may be able to stand on inside some parts of the planet.

Cold Storage

  • Sometimes, if the yeti is going up uncharged and hits an icicle enemy, he will destroy the enemy nonetheless. The criteria for this glitch are currently unknown, but it seems to happen when jumping on a regular pole right after a super pole.
  • If the player dies during a level, sometimes the next level will start.

Cooped Up

  • If the player continuously jumps around on the first string of rope, the music will restart itself when a jump is made.

  • After the player has defeated the Behemoth, sometimes the game will stop. The players will be able to move around in the screen, but nothing else will happen.
  • When fighting Talos, if the player(s) pause before or while he is coming onscreen, he will stop in the middle of the screen and not move. The player can attack Talos as much as they want and he will not die. After depleting his health, his healthbar will begin to move from the starting spot to the left side of the screen.

Enemy 585

  • Sometimes when Turner stops a squish block, the block will stay stuck in that position.
  • Sometimes, for no reason at all, Enemy 585 will die when just walking on a flat surface. This is probably caused when a hazard like a squish block or Turner (when he has spikes on him) was in that area, then suddenly moved away.
  • Sometimes, when Turner and Enemy 585 move into the same space at the same time (usually Enemy 585 is falling and Turner is going up), Enemy 585 will get stuck inside Turner.
  • When Enemy 585 gets launched by a spring and lands next to a one-block high wall, instead of going over the wall, he will turn around and walk the other way.
  • If Turner turns while Enemy 585 is climbing him, then Enemy 585 will climb inside Turner and walk out of him after doing so.
  • If Enemy 585 dies while the player was pressing either the left, right, up, down or "F" key, as the level gets restarted, the action corresponding to the key that is pressed will keep on running until the player presses again the key for that specific action to stop it.
  • Moving fast at the start of a level, and continuing this speedy movement, will cause Turner to move uncontrollably when the level resets.
  • In some places, when Enemy 585 has to climb up a long stretch of blocks, he may unusually just move through them.
  • When Turner somehow collides with Enemy 585, Enemy 585 will get trapped in Turner. This is only possible in 1-2.
  • Sometimes, if Turner is placed as a stairway and Enemy 585 is going up, if the player turns Turner fast enough sometimes Turner may glitch and Enemy 585 will randomly start going up until Turner ceases switching.
  • When the game is paused, the timer might keep counting.
  • When Enemy 585 falls and the player pauses the game, Enemy 585 will stand on a part of land at the side.
  • After the ending for the game is shown, when the player goes back to the main menu, no music can be heard, but the barking of the guard dog can still be.

Feed Me

  • Sometimes, if the player bites deep into a wall, floor, or ceiling, they will end up inside said area. The venus fly trap might even fall off the screen.
  • On the level Tomato Nursery, if the player eats all the bugs, then goes back to where they started, then bites the ceiling enough, the Venus Fly Trap's head will get stuck, and if they bites the ceiling above it till it gets on solid ground, it turns into a shortcut that is an easy way to get through the level.
  • When the player completes the last level, the "continue" button will sometimes be gone, thus the player will not be able to see the end screen, and sometimes the "submit score" button will be gone.
  • Sometimes the camera will stop tracking the fly trap, causing it to go off the screen, but allowing the player to still remain in control of it.
  • In the level 7, "the pit", the fly trap can sometimes ride the vine up through the stone walls.
  • Often times when the fly trap if the player attaches to a surface quickly while falling, the fly trap's pot will swing horizontally to where the head is supposed to be, while the head is seen clamped onto nothing.

Final Ninja

  • If a player fires a rope at the top of a distant wall and travels towards it at a sufficient speed, it is possible to go through the wall. This is most easily demonstrated during level three.
    • When going through a wall that is bordering an out-of-bounds area in level 3, Takeshi will freeze into his falling pose. If the game is paused and then continued, Takeshi will cycle through most of his animations, with ones such as turning invisible missing. During the cycle a copy of his arm will spin around in the rope holding position.
  • Occasionally, if the player falls an extremely far distance and dies, the ending for the game is shown. This glitch can be done on level seven.
    • During a level, the ending will begin to play on the screen, and it will show the ending and say that the player has beat the game. However, when the player goes back to the menu, they will still have to complete the rest of the levels.
  • Sometimes, when the player causes an alarm to go off, a laser sentinel will not be fully ejected from the ground and will be stuck halfway in the ground. The laser sentinel will still move, however.
  • Sometimes, after the player completes level ten, the sounds of Defense Robot Alpha disintegrating will be heard throughout the level.
  • When playing Final Ninja on, if the player views the high scores, they will be prompted to visit to view them. This is because in the game's programming, if the high scores cannot be loaded, then the game is programmed to display a message prompting the player to play the game on, as high scores not loading is usually a sign that the game is being hosted on a website other than
  • Sometimes the camera will not scroll until player has reached the other side of the screen.

Final Ninja Zero

  • When Takeshi fights Maxwell Merlock the second time, if he dies after killing him, pressing try again at the You Died! screen will make the game proceed to the next level anyway. This glitch has been fixed.
  • On level 18, when the player starts, the lift that Takeshi came out of will sometimes be still there. If the player walks into it, the player will proceed to the next level. This glitch has still has not been fixed, and probably deliberately left in due to this glitch's popularity.
  • Sometimes, when Takeshi presses space to get a message, it takes the player to the next level. Other times, it may restart the level.
  • If Takeshi fires a ninja rope into a surface or object that it can't attach to create a rope on (white lab walls, blue shields, etc.) , Takeshi's hand will be frozen in place like it would be if the rope had connected. This can be fixed by jumping.
  • In any level, when going into stealth while entering the lift, Takeshi's eyes may stay at the point where the lift was, before progressing into the next level.


  • On level 20, if the player goes to the semicircle seen when starting the level and continuously rolls to the right, Fluffball would be on a invisible platform. No matter how much the player rolls towards the right, Fluffball would never "fall off". However, if the player rolls too much and tries to go back to the main level, Fluffball would "fall" and the game over screen would be shown, or the player would never be able to get back.

Frost Bite

  • On levels where the player can't make a full jump, they can hold "up" for rapid jumping.
  • If a jump-vulnerable enemy comes near the player while said glitch is happening, it will die as if it were jumped on.
  • On Mount Neverest (level 10), at the boss stage, the player will be damaged if walking over a certain spot near the exit door.
  • Rarely on level 8 when the hooks are shot with the grappling hook, the Eskimo will be pushed to the right and the grappling hook's rope will extend until the Eskimo has reached the edge of the screen. This also prevents the player from moving.

Frost Bite 2

  • There is a glitch that if the player dies, and they are on their last life, the game will sometimes respawn the player, so the player can die as much as they want, but the Game Over Screen will never come down unless the player quits the game.
  • Sometimes when the player dies; the grappling hook will be frozen.
  • Sometimes, when the player loses a life, they will continue to play, but their energy will be at zero. If the player is hurt at all during this glitch, they will lose another life
  • If the player is in the mesh area on Mount Neverest and shoots at the very top point, they will be shot up inside the rock, and will fall slowly. During this time, the player can shoot above, and hit the checkpoint. This saves having to get through the actual ice path.
  • On Level 6, Glacial Slopes, if the player hits the first ground next to the Eskimo at the right, the player may sometimes jump upwards or even fall off the screen, forcing the player to quit and restart the level. This can also be performed in other levels.


  • If the player is shooting him/herself up, and is pressed against a wall, then this glitch can happen. If a red sphere is coming at the player while they are shooting, then the player will not be harmed. However, as soon as the player releases the fire button or tries to move, they will die.

  • On level 18, the player can blow the octopi through the wall.
  • On level 22, if the player blows the fan pointer above of Hot Air while on the starting platform, the spiked cage will not pop him when it passes him. This results in easy completion of the level, along with easily collecting the stars. This is also the case on other levels, but it does not benefit the player as much as on this level.
  • On level 22, if the player lets the hot air balloon sit still and holds the fan over the balloon, it is possible for the cage to go completely through the player, enabling the player to complete the level easily.

Hot Air 2

  • On level 19: Cooking on Gas, if the player starts the level without moving Hot Air at all, blue fires will come and touch Hot Air where it is, and the balloon won’t pop.
  • If the player blows Hot Air into spikes very fast one, two, or three times, the box the balloon is holding will actually fall up, and the Music will get louder and louder and louder and louder.

  • Sometimes, if the player dies above a star, when falling down the driver of Hot Air will grab the star.

Hot Air Jr

  • Sometimes the game will malfunction and the stars will be showed twice, and the screen will become grey. There is no way out of this glitch. This forces the player to refresh the page.
  • If the player defeats giant spike ball in his fourth phase and has not yet surrendered, he will be destroyed but any of the endings will not pop out. This makes the player have to restart the level.
  • If the player defeats the giant spike ball in its fourth phase, another glitch can happen if the player goes under the ball when changing to its last phase (which is the defeated one), when falling, the ball will push Hot Air Jr into the wall. After this, the balloon will start falling slowly with no chance of getting out, thus, the player will be forced to restart.
  • Sometimes during the fight with the giant spike ball, if the player is killed, the player's gondola will detach from the head of the balloon, but the player can still blow Hot Air's disembodied head around.

Ice Breaker

  • Sometimes, if the player loses, clicking the reset button will let the player progress to the next level.

Ice Breaker: The Red Clan

  • If an un-frozen viking falls into the boat, but is knocked off for any reason, the Failed! message will appear, but clicking try again will proceed to the next level. This glitch has been fixed.
  • If a player clicks reset immediately after a viking dies, the level will restart, but the Failed! message will appear.

Ice Breaker: The Gathering

  • In rare occasions, the rock will go through the ice and get stuck in it.


  • If the player gets hurt in two different ways (such as getting shot/hit/bombed and the ice falling), the player may take only one damage.
  • Sometimes when the player shoves the ice block off a cliff and it falls on them, they will be stuck inside it.

  • If the player goes to the high scores menu, it appears like the distributable games high scores menu.

Mallet Mania

  • Sometimes, when the ball lands on a magnetic spinner tile, they will still be able to control the ball's direction. This especially happens when playing in multiplayer mode.
  • The zapping action transforming the ball into different types may still appear sometimes between shots, even when the ball has not rolled over a pickup or been gambled for.
  • If the player's ball rolls into a wall, typically against a magnet, the ball may vibrate and never stop moving, thus making it impossible to continue the game.
  • If the player is is another tab when the game starts in background, the startup will loop.

Mega Mash

  • On level 2, in the first Blastman Joe section, if the player waits around, eventually the mouse gets stuck at the bottom of the screen and then they don't have to dodge it or blow it up.


  • If there is a mine right on the player, when they start to move, it will start ticking. If the player jumps straight up in such a way that he will be hit by it as he is just about at the peak of his jump, the player will be rocketed into space. This glitch has been partly fixed, as it now has a lower chance of happening, but still can.
  • If the player is killed while using pieces of eight, they will be able to still use them until they run out.
  • The player can use a voodoo doll on a dead character and throw it. It is unknown if this is a glitch, though.

  • If a player clicks an unlocked level, then pushes one of the arrows on the side while the screen begins to transform into the instructions page, the background of the level will change based on how many times the arrow was pushed.

  • A frequent glitch that may appear is that when a player finishes a level, they may begin to move uncontrollably in a certain direction, or even stick out their tongue. If the player tries to fight it, they may end up wandering off the level. This glitch can usually be fixed by pressing the same key that corresponds to the action the Troll is going in. (For example, if the Troll is moving left without the player pressing the left key, the player can press the left key, and the Troll will stop.)
  • If two players eat one block at the same time, they will both have the block in their mouth, and can use it as normal, except that when the second spits it out after the first spits it out, the block first spat out will turn invisible.

Swindler Glitch 1

The glitch

  • On the second last level, in the part where there are two wall yellow goo and the inflatable yellow goo, if the player gets near the wall and touches the inflatable yellow goo, the player may sometimes get stuck inside the wall forcing the player to restart the level because is after that impossible to get out of the wall.

Temple Glider

  • If the Egyptian bird is killed while in the hands of some quicksand (by an arrow) there will be an invisible bird inside of the hand's clutches. The player can still control the Bird only it escapes, or is dragged into the sand. This glitch is most easily done on level 16.
  • Sometimes random feathers (that appear during direction changes, deaths, and respawns) will appear at random places for no reason. They also will not float down, so they stay there for the rest of the level. The cause of this glitch is unknown.

Test Subject Green

  • In level two, if Blue were to be killed by the monkey green enzymes, these green creaturres would randomly start moving in between different areas between teleporters while not going through the teleporters at all. It would also become impossible for the player to destroy the enzyme or the green enzyme destroying Blue. Later, a Nitrome blog post reported that the glitch had been fixed.

Level two TSG glitch

  • On level 11, if the player died in a certain scenario, they could be trapped with no way out. This glitch was later reported fixed.
  • In Level 15, if Blue jumps on a certain teleporter right above a laser, he will sometimes die, as if he landed on the laser instead of going through the teleporter to the one above it. (See image below.)
TSG Level 15 Glitch

Level fifteen TSG glitch

  • In level 20, on occasion when someone reaches the end Blue collects the food (as meant to), gets sucked up the tube (also as meant) but the level does not end & the timer continues.
  • Sometimes, when Blue is killed and is sent back to his nearest checkpoint, he can do a super-jump by rapidly pressing jump and shoot at the same time while invincible, which may shoot Blue off of the screen, forcing the player to restart the level.
  • It is possible to get to the other side of a teleporter if Right and Left keys are pressed steadily and fast if Blue remains in the middle of a teleporter.
  • If the player holds down the shoot button and the up button, right as Blue is spawning, Blue will rocket upwards in the air. Also holding down the Left or Right keys can adjust flight direction.

Test Subject Arena 2

  • In multiplayer level 1, it is possible to get trapped between two teleporters at the top of the level.
  • In any single player level, it is possible for the player to kill themselves, though they will not respawn until the time runs out.

Thin Ice

  • Some circles the player makes on the ice will not drop down.
  • Sometimes, rarely, if the player makes some shape in the ice,and it drops down, sometimes the shape in the ice will stay there till the player dies, or restarts, or goes to the next level.
  • This glitch happens a lot in old games; if the player is playing a level, then goes back to the title screen, the music from the level will be heard on the title screen.
  • In any level with bird monsters, the smallest bird monsters can get stuck in the sides of the ice bordering the level. This is especially apparent in level 18, where there are many small bird monsters hopping around. This glitch, while only occuring very rarely, means that the player cannot complete the level, since the Eskimo cannot draw a circle around the stuck bird monster. This also means the level must be restarted.
Thin Ice Glitch

  • There is a glitch in the game where the digging robot won't explode when it hits metal.
  • Sometimes a bullet fired by a robotic squid will stick to the wall it touches. This mainly happens when the robot is killed right after the bullet is shot.

    The stuck bullet glitch. Notice that the squid is in normal form, proving that the bullet is indeed frozen.

  • Pausing the game while a bomb is present may result in the bomb detonating.
  • A glitch exists in the game Twin Shot 2 that can only be access while using level skip. If the player beats a level, and presses level skip without clicking "Next Level," the screen will not appear normal and the letters will be overlapped.

  • When the player forces an enemy into a small space, it will go through the wall.
  • If the player gets a bonus level while using Nitrome Touchy and completes it (whether or not they die), the smartphone screen will say 'Level failed'. This allows the player to get even more lifetime coins.
  • If the rock block in level 8 is shot enough, the rock block will levitate in the air, and if shot enough, can land on higher platforms with this glitch, which causes another block to appear in the glitched original spot on the ground.

Worm Food

  • Sometimes when colliding with a rock or a spiked idol, the Giant Worm will get stuck inside, trapping (and causing damage, for the idol's case), until either time runs out, or the worm dies.
