The edges wrap around: fly off one side and you come back on the other. Extra life every 10,000 points.
Fly a small spaceship through a field of floating space rocks. Shoot a big rock and it breaks into smaller, faster pieces, so keep moving and watch every direction. Collect power-ups for triple shots or a shield, and look out for the flying saucer that shoots back. Clear every rock to start the next wave.
