First i would like to say that i don't own any of the sprites, backgrounds, music, ect. it's use is for educational and entertainment purposes. Second you will die the fist 2 rounds. Third is controls: Shadow: Sonic: A=left A=left D=right D=right W=bounce W=bounce J,K,L=attacks J,K,L=attacks Super sonic: The rest: A=left A=left D=right D=right S=down W=bounce W=up J,K,L=Attacks J,K=attacks I,O,P=Specials NOTE:FOR the rest not all button work for some.
