Great idea with the combination of dead animals!
I was missing a few small things in the mechanical aspect - I didn't expect destroyed animals to come back to life, sacrificing parts was a bit strange, but everything was fun. Especially the basket (read: mass grave) for body parts. :)
But I'm missing *something* (and I've been trying to figure out what it is since the weekend). Maybe the supposedly funny naming of the mutants, maybe legendary parties, the little effects of the characters, something. maybe some other piece of morbid comedy and humor, I don't know yet.
