I played this a while back and oh boy, this game clearly isn't for pussies.
The fighting system is harder than what you've ever encountered in a fighting game.
The game is played by relaxing, holding, extending or contracting the various joints on your character and hitting the spacebar to advance time by a user-specified amount, the default being ten frames. When properly manipulated, one ragdoll will strike the other, and if enough damage is inflicted with a single blow, a limb or body part may be dismembered, or fractured. Through careful manipulation of the ragdoll's joints, arbitrarily complex attacks can be performed.
