1. I haven't really made 3 or 4 player to work yet(there probably aren't even enough keys on the keyboard for that many players to be comfortable on one computer), so if Player 1 or 2 dies, then the other of the two will win. And there still is problem that when you get hit there's no invinclibility time so sometimes you can die when Super Mario, need to fix that.
2. It's due to a simple array bug, I've fixed it already.
3. I took that out for the next version, instead it will be "Internet Play".
4. The game does seem to run a bit fast on newer computers, so maybe I should put a delay counter so the speed is adjustable.
5. I found this problem; Mario can sometimes fall through floors if he has a great enough downward velocity. Right now I don't know what to do about that, but I already made it so that if he falls through the bottom floor, he regenerates ON the bottom floor instead of sailing into oblivion forever(or until you hit Escape).
