Arrow keys to move, space to fire laser. When fighting the gray command ship, blast it's antennae, first, but it will only work once. The only way to beat the command ship is to blast a torpedo that the command ship fires, while it is touching the ship. Tri-fighters take shield power from you when they touch you. Torpedoes take two.
Ectoplasma helped me come up with the idea. Starwars, too.
