Use the left and right arrow keys to move. Use the space bar to go into the sun form (IDK what it's called...). Use the down arrow to shoot (You don't shoot out anything though. It's just the shooting animation.) Last use the up arrow keys to jump.
This isn't the smoothest test ever because he is a little glitchy. I didn't know how to fix it. This was the best I could do and the hardest work I've ever done so please don't judge me. Also the music, sprites, and background are not mine. Their Nintendo's.
