Just my ideas. Arrow keys to move and jump. I will add on to this because it is basically my storage for attacks. It is survivable but I don't know about a no-hit. Tell me if you no-hit, okay?

I was going to add a platform sprite into the mix, but I just didn't get to it. Added SpiralBone Attacks! Made some crazy bone attack I work on this when I am bored.
