Up arrow key to go up. Down arrow key to go down. Space key to fire TNT.
All credit to @ThePancakeMan for giving me the idea. You should check out his version http//scratch.mit.edu/projects/29802868 . PLEASE NOTE: Mario isn't a bonus. I just thought it would be funny to add him being chased by the creeper. BUG: Sometimes the wither boss glitches out where you can't hit him and he doesn't move. You have to click the green flag again. I'll try to fix it but for now I can't. D:
