It's much more confusing than the video makes it seem. Basically every little joint on the guy and all the knobs his torso are made of are muscle or joint objects, and you can select various states for them like hold, contract, extend, relax, etc. The game is played out in seconds. The time counts down while you tell your various parts what you want them to do, and you can see a little ghost image of the next maybe second or two that will happen after your decisions. Once time is up, your guy performs those couple seconds of movement and you an begin selecting new actions for the limbs. Your opponent is also doing this simultaneously. Eventually you'll make contact and you'll score points for how much damage your attack is doing, and your opponent gets the same. So it's sort of a slow-motion, one-move-instant-kill fighting game. And it doesn't *look* interesting to the outside viewer until the match is over, because then you get to watch all the crazy shit play back in real time, where it looks like the video (or much funnier, since when you first start it's hard to get the guy to do anything but fall over on the floor in hilarious ways). The video is all one-sided, whereas against an opponent you'll have both guys trying to kill each other. It's very entertaining and sort of addictive.
