Hot Air Jr

Hot Air Jr. is an adventure game released on June 28, 2012. It was first hinted in a .gif of an enemy from the new sequel on the Nitrome Blog on March 3, 2012. Gameplay from Hot Air is retained, with the player using a fan to control Hot Air Jr around the stage while avoiding enemies and hazards. Hot Air Jr. is also the second Nitrome game to have a demo.

Controls
Mouse - Move/blow fan

Levels
Hot Air Jr. consists of 17 levels, 12 which can be accessed once the previous level is completed, 4 secret levels that have to be unlocked via the collection of all stars in levels, and a level accessed by going into Squeak's dog house. Level are divided into 4 rooms, and for the first time in the hot Air Series, the player has to traverse a house where the levels are doors, the house acting as the HUB of the game.

Basement (level 1-7)
This is the first room the player gains access to at the start of the game. When the player starts, a locket gate is blocking the right exit of the room. A Key is necessary to open it, which is obtained by following the level doors all the way to the seventh level.

The bottom level of the house is safe, while the upper hallway is lined with spikes on most of the ceiling and floor. Where level 7 is is where the key can be found, and once brought to the door, allows the player to access outside. Even once the player has opened the gate, even when they leave reload the game (such as when the click their browser's back button or close their browser, then go back to the Hot Air Jr game) they will start back in the bottom room, and may (but not all the time) have to go retrieve the key.

On the far left of the room are stairs, which lead to the changing room.

Level 1
Enemy: Boot

Rooms: 1

The player has to wait for the Boot to jump high up, off the screen, then they can pass underneath them.

Level 2
Enemy: Large fan

Rooms: 2

This level has two rooms, both which have large spinning fans. The player has to go up, horizontally left, then down to get to the entrance of the second room. Located on the top left is the first fan. The second room contains a restart pad. To get to the finish pad in this room, the player has to travel horizontally right until they reach the diagonal patch of spikes.

When there, they have to travel upwards until they get to to the ceiling, then horizontally left to the end of the middle spiky segment extending out of the wall. The portion where the player has to move upwards is where the second large fan in the level is found. This enemy can be avoided by going around it.

Level 3
Enemy: Swords

Rooms: 1

This long level involves having to go past swords found in the floor and ceiling of parts of the level. The first section can be easily traversed if the player holds the fan to Hot Air Jr's head and goes past the spikes without stopping, until coming to the mini swords.

As these enemies move automatically, the player should only move through after the first sword goes down then retracts enough the player can enter. As with the first set of swords, the player should use the Fan-to-head Hot Air Jr. technique. The third set of swords are not like the first, these ones move faster down.

For traversing these ones, the player should wait until each pair of swords retract out, then while retracting back in, go through the gap that appears. This should be repeated for each sword in set 3 until the player reaches the end.

Level 4
In this level, Hot Air Jr. is faced with a spike maze. There is also a pink spike block that follows Hot Air Jr. around the level, and homes in on him every few seconds.

When the player starts, go up for a bonus star, then go under the homing enemy. Go all the way to the left and go up. Continue and turn right for the two stars. Follow the maze of Spikes when they gather around Jr, soon, Jr. will find himself at the finish platform.

Outside (levels 8-12)
Outside is unlocked once the player retrieves the key from the right of level 7's door. Outside, a few Spike blocks are found, and a roaming Purple bat. This room has a semi-secret level, the dog house. At first nothing pops up to indicate it is a level, but when landing on the base of the house, the level is entered. Levels 10-12 are on individual platforms that are placed high up. The top left of the room leads to the upper room.

Dog House
Dog house is not given a numerical level number, only referred to as "Dog house". At first, in the room the level is accessed, nothing pops up to indicate it is a level. Only when the player lands on the base of the dog house it is entered.

Level 12
Level 12 has the only and first boss in the game. There are two outcomes in the level, both outcomes that give different endings. (please note that, although both videos are walkthroughs that show how to kill the boss, any of the walkthroughs that show how to plummet the boss to the ground and cause him to surrender can be used to complete the level) Good ending walkthrough

Evil ending walkthrough

Upper room (levels 13-15)
The upper room has 3 Spike crusher blocks, and between each crusher block a door that leads to a level. Each level in this room is unlocked once the player has gained enough moustache stars (a moustache star is obtained when all the stars in a level is collected). At the edge of this room is wall, which on the opposite side has the door for level 16.

Level 13
Moustache stars needed: 6

Level 14
Moustache stars needed: 12

Level 15
Moustache stars needed: 14

Spike-ridden hallway (level 16)
This room is accessed from the room the changing room is found in. To get to it, the player has to blow the balloon through the bottom part of the wall placed on the right.

This will bring the player to a block background. Going up will being the player to a winding hallway, riddled with spikes, which at the end has the level 16 entry door. Here, the room shakes, as the spike crusher blocks cause vibrations that stretch to this room.

Level 16
Moustache stars needed: 16

Changes

 * A background consisting of coloured hills stretching out of cloudy air with the hills against a coloured background, are not used in all levels (as seen in the March 13th 2012 preview image). However, this may be because the game takes place in a different area.

 * Most platforms will not contain Spikes.

Demo
On May 12th, Nitrome released a demo of the game.

March 3, 2012
Nitrome revealed a .gif of a bug-like enemy that is to appear in an upcoming sequel. Fans were directed to tell Nitrome in the comments on Facebook and Twitter what they thought the sequel was. After the release, the preview image was revealed to be a floating pear

March 13, 2012
Nitrome revealed their "cryptic sequel" to be Hot Air Jr, and provided an screenshot of one level of the game. The screenshot never actually appeared in the game

March 22, 2012
Nitrome revealed the official name of the game, Hot Air Jr. Nitrome said also that it will be easier than Hot Air and Hot Air 2. They provided another screenshot of the game which turned out to be a beta image.

May 12, 2012
Nitrome released a demo for the game on their site. This was Nitrome's second demo.

Beta elements
The only known beta elements are a few of the preview images provided by nitrome. The March 13th image (2nd preview image) showed Jr. in a room with three floating pears. It is likely this image was only to show what the art would look like, and not an actual room, as the room has an unusual setup consisting of a yellow block and a breakable block.

The second and last beta image is the March 22nd preview image (3rd preview image). The image shows level 15 of Hot Air Jr., but with a different background and different coloured blocks. The section shown is the second diagonal hallway.

Glitches

 * On level 9, when all the teeth are destroyed with the Floating mines, the player can die without touching the gums. This is likely due to the player colliding with the hitbox, as hitboxes can only be square, and not go completely around an object if it is curved or irregularly angled.

Trivia

 * The Hot Air Series holds the record for the longest amount of time waited until a sequel was made for a game, Hot Air Jr. being released 5 years after Hot Air 2.
 * It takes place in a later time than the previous two games, the player is controlling the Hot Air Balloon's child.
 * If the player dies but the driver gets the key, it is still obtained.
 * It is strange why the house has spikes and enemies when it is supposed to be private. This is probably to make the game a little more challenging.
 * It is unknown why stairs are put in the house, because the bean people are too short, and they can just fly up in their balloon.
 * The demo actually explains or shows most of the elements used in the game like hidden passages, keys, and more.
 * This game in the Hot Air Series that has some walls that do not pop the balloon.(denoted by spikeless walls in Hot Air Jr.)
 * As in Hot Air 2, the player can customize the character's balloon.
