Just heard about a game called Toribash.. I downloaded it (Free at http://www.toribash.com) and it seems kind of cool.
Thing is, I can't figure out how the heck to make your guy fight xD
You press different muscles and order them to contract/extend/hold etc, and your goal is to get your opponent to hit the ground first.
Ordering different muscles around, you can execute MAD tricks and combos.. I've just not gotten there yet :o
