RIGHT/LEFT: Turn. Ship bounces off walls. UP: Shoot bullets, hold down to charge. When released, your ship will shoot that amount of bullets in a high concentration. Bullets bounce 5 times. Lives and Charge are displayed at the corners. DOWN: Shield, any opponents bullets that hit the shield bounce off and turn your color. However the shield slowly drains health so use with caution. 2 Player: WASD.
