Gunbrick

Gunbrick is a Puzzle Platformer Nitrome game released on April 20th. In this game, the player controls a square block, Gunbrick, guiding it the end of a level. This release is very different from other Nitrome games, because it does not include a menu screen, a credits screen, or a level select screen.

Controls
Left, right - Move (tilt) Gunbrick to one side.

Spacebar Up, down, spacebar - Shoot Gunbrick's gun.

Icon game
Nitrome labelled Gunbrick an "Icon Game", because the player is able to play the game inside the game icon. The screen fits within the icon in the game selection menu, though the screen can be expanded by clicking on the screen to access a menu, and clicking the expand button.

Hazards
Red Shooting Blocks - Red Shooting Blocks constantly shoot a stream of red bullets that can injure Gunbrick on contact. However, should the bullet hits the white side of Gunbrick (the back), Gunbrick shall not be hurt.

Interactive Objects
Checkpoints - Checkpoints are "save points", at which Gunbrick can respawn and continue should it die.

Green Blocks - Green Blocks are found throughout levels, and can be arranged into access paths by hitting Green Buttons.

Trivia

 * Many of the components in the game are similar to those in Fault Line.
