There is no way to die!! Also the balls should be removed when they hit the edge. The green balls should be added at the location the blue ball was hit.
I think this game is fun and has a lot of potential, but it needs a lot of work... Sometimes the rounds hit, but don't kill the aliens, and I think only one shot should come out at a time. This is a preference, but I would change the "w" and "s" keys to the "up" and "down" keys.
