Gunbrick

Gunbrick is a puzzle platform game that consists of ten levels and a boss. The player controls a square block called gun-brick. It can only rotate left or right. One side of the brick has a shield that can reflect bullets and the opposite has a gun that can destroy blocks. When after rotating, the gun is on one of the sides and there is room to move, the recoil of the shot can be used to move left or right without rotating. When the gun is rotated to be at the bottom recoil can be used to launch the brick in the air, with small bursts in succession to reach heights. The combination of these mechanics is used to get to the level exits. Gun-brick needs to move past enemies, navigate or create a passage in the environment and shoot opponents. Checkpoints can be activated during the levels. A single hit is immediately deadly.

The game was created to be played inside the Nitrome product's icon of 50x50 pixels, but the gameplay window can also be made much larger.
