Welcome to @PaperMarioGuy289's game!!! There are 31 levels, and 3 different playable charicters! This is my first game, so be nice, anyways... Move around, Left key, and Right key. Jump, Up key!
I was sick and had nothing better to do, so I added the songs you wanted and fixed some of the laggy code. Hope you like it and can't wait to see your next game! :) P.S. Feel free to ask whenever you have any coding questions. I'd love to help.
