In Cube, you control a transparent cube that can move in four directions, with one side always connected to a solid object like a block. There is no gravity in the game, so you can move your cube along all sides of the blocks that make up the level. The goal of each level is to reach the exit panel, which is invariably tucked away behind barriers or hazards or floating on a distant, disconnected block. It's your job to hit switches that make barriers retract or make new blocks appear to create a path to the exit panel.
