This was quite a lot of fun! :D
Made a complete hash of my first attempt (don't ask - I even managed to crash THOUGH the star destroyer model!), but nailed it the 2nd time.
Good graphics and sound. The controls were a little iffy when aiming at the top & bottom orientation. I assume that's to stop things getting too funky. Didn't help me on the last phase coz I thought "I know, I'll attack from the bottom!)
Overall, a really good entry - congrats and good luck! :D
