Arrow keys change the direction of the player ball. It never stops moving, and you die if you touch the edge, so be careful! You score points in the following ways: shooting the enemy ball (space bar; hit the enemy for 50 points), the color changing ball that bounces around and kills you if you touch it, touching the blue ball for 10 points, and touching the purple ball for 5 points. you also score a point for every second you stay alive. My best is 1165, see if you can beat that! To start a new game, click the green flag. Best by other people: 1e+42
