Looks good, I am giving it a try.
Edit: Tried it, here are my thoughts:
-Very solid made, it is fun to dodge the enemy laser shots and asteroids.
-Explostions are nice and have enough debris going off.
-Sadly ist not timer based, so my dying graphics Card slowed it down during Level 2.
-Music is also pleasant to hear and not anoying which is a plus.
-The rockets are well done, quite fun to fire those.
-The Level Wall hit me out of nothing, maybe you shouldn´t allow the enemy spacecrafts to fly outside this boarder, or make it so that Radar only detects them when they are inside the boarder, or near enough to the Level boarders to hit them with the laser.
-Menue looks very professional and great, intro looks good, maybe a bit Long (didn´t figure out how to skip the intro). Warp sequence is a bit Long, maybe reduce the time the ship takes before it starts to warp.
-Warp effect was very nice, liked it a lot.
So in conclusion i say, i would played this longer if it where timer based ( or if I had a new graphic Card that won´t die on me while playing this ).
