A very cool micro-RPG! It would be great for a spontaneous game during a rainy day, at night while out camping, or at a boring gathering/party with nothing to do. A real "beer and pretzels" game! This would be a good way to introduce RPGs to newbies, as the system isn't very rules-crunchy. My only complaint is that, unless I grossly misread the rules, a lot of the animal category entries give you penalties instead of bonuses. That's like making a hero with the "powers" of being completely blind and deaf, but nothing else to compensate for it. That's why I rated this 9/10 instead of giving it a full 10.
Anyways, great work!
