w, a, and d to move knuckles, s to punch (hold s to double punch), q to ground pound. for shadow arrow keys to move, down to kick, m for secondary attack, and space to teleport and kick knuckles and send him flying. lol. if singleplayer and you select knuckles, controls same as shadow
winner of each round gets a chaos emerald, 7 rounds, whoever has more wins. let me know in the comments if you think the color of the lightning should be blue or orange for shadow
