All you need to really do is remix. Don't change anyone you're not beating up (besides Garfield), and things will be ok.
changes: made the guy do stuff while waiting (the score's now more flexible than displayed) fixed the HP bar's handling of decimals (now it won't show them(I didn't make a sprite for that)) made this as Idk if other people will do stuff (and I want to know who's remixing)
