Shift: by Armor Games Inc. is a challenging and unique puzzle game. It will make you think in a new way. You are subject 32763 in an experiment. You just have to find your way out the door on each level. Sounds like a mouse in a maze, right? This maze has one big twist, though. There is a shift button on each side of the screen. If you tap one of these buttons, the black and white areas on the screen swap places. The background color becomes solid ground and the solid ground turns into the background. When this change happens, the screen and your guy on the screen flip over to compensate for the change.
