You are a velociraptor and fight monsters and graft new body parts onto your character, mutating your creature in bizarre ways.
New body parts increase your food requirements, better parts costing more calories. Don't have enough food? Eat your offspring! Want those fancy wings your opponent picked up? Attack them, rip them off, and add them to yourself!
Fight, survive, reproduce, cannibalize, and win!
