This little freeware game really has me intrigued. The idea is to allow the player to control all the core muscles of his character, individually, in order to perform precise movements. You can tell each muscle to flex one of two ways, or just tense it, in order to keep it from moving. The goal is to do more harm to your opponent than yourself, but in all honesty, 95% of my matches turn into gay sex, despite my best efforts.
