arrows - move X - jump S - run/fireball
My first foray into clone-based tile scrolling. So far, I've added the powerups, the flagpole, and coded the warp pipe (although it is very glitchy). Enimies coming very soon. I could probably make the entire game using this engine, but I'll have to see. I'll continue to make this better and post the updated versions as I go along. I actually developed this in Scratch 2 Offline since I don't have much experience with 3.
