The controls are as specified for each character at the bottom of the screen. The up-most control is fire a rocket that can kill players on a direct hit and destroy small sections of line and the lowest control is the stealth jump, your character teleports forwards a bit (once per round.)
I did my best. Enjoy. All I really changed is the ability to shoot. You can also change the amount of players by going into the backdrop and setting the color states to 0 for each color you don't want in.
