Shift Puzzle is a platformer that is fundamentally different, in that it makes you do jumps, but also lets you "flip" perspectives. If you were black, you shift to white (and the map turns inside out, sort of), which may be the only way you can get to the "exit". The main problem I see is the "jump" is not a dedicated button, but instead relies on "multi-touch", in that if you hold down right, then tap left, you jump while going right. Thus, the control scheme is a bit... weird. But the idea of shifting perspective is a very good one.
