Use the arrows keys to move, but you can only move when jumping. Don't fall into pits. To defeat the bosses you need to touch them. It's not that hard unless you're really bad at platformers.
Ok, I know I said Cube Adventures was going to be my entry for @will_wam's contest, but Cubey couldn't move unless he was jumping, so I decided to live with that glitch and make this instead. I am going to make a sequel! Music: Jumper by Waterflame Jumper 2013 by Waterflame
