Credit to Soundimage.com for the music-thanks a lot! Credit to JR 01 and, of course, grazer, for help with the code. Use C for coordinates, F to full stop, arrow keys to move, spacebar to shoot, and, once you've leveled up:

LVL 1: V for Phaser

LVL 2: Faster healing

Lvl 3: X

Lvl 4: Warp Engine

Lvl 5: X

Lvl 6: Photon Torpedoes

So far I've had success with this game. There are:

Working enemy types, randomly generating solar systems, self-defending space stations, a powerful LASER upgrade, and much, much more !

Enjoy! :)
