Tadah! Since everyone was hurting themselves, this is a new game.
The Wall starts with 1 HP. Every time you attack the wall, it loses 1 HP. Everytime you hurt yourself instead of the wall, it gains 1 HP. Every time you do a move, the group (good guys and bad guys) gets 1 coin. Once you get enough coins the wall will gain or lose more HP.
Ex:
Wall: 2 HP Goodguys: 1 coins Badguys: 0 Coins
I jump off a cliff!
Wall: 1 HP Goodguys: 2 coins Badguys: 1 Coins
I headbutt the wall (Thats both, you hurt yourself and the wall)
