press space bar to jump, press the A button to shoot a fireball, and obviasally, arrow keys to move. plot: kill bowser by shooting fireballs a him, I'f he hits you, he gets healed, I know in the original game you have to throw bowser at a bomb, but I'm not skilled at scratch in any way, shape, or form, so I could'nt figure out how to make that happen. :(
