A start for a game. I changed the big Mario costumes. Do not remix unless your name is kingdomfan4 or PikaPower. Some things to work on are: bullet bill, koopa shell, goomba hurting mario, fire Mario scripts (I'll do the costumes), areaction that makes the death sound which is in mario's databanks, and (no offense to Pika Power) a better script for mushrooms.
