A couple weeks ago I posted a game called Shift. This week's game, Yin Yang is kind of similar, but this game has you playing as two different characters which must help each other reach the goal. The concept is very cool (it's either inspired by or stolen from Negative Space, depending who you ask.) Unfortunately, sloppy controls and collision detection make it less enjoyable than it could be, but it's fun and unique enough to be a fun diversion despite these issues.
