Nit picking a bit, sorry.
I see potential for a good game if you redo a few things.
The movement could be better, real looking.
A much harder game, I wasted those Tie Interceptors with ease.
The graphics could be a little better, perhaps some things moving around in the backround.
I loved the music, the greatest part of it infact. The music was crystal clear, no static and no skips.
X-wings fire red lasers not green.
Tie Interceptors are faster than the X-wing.
Also if you redo it (I hope you do because the game was good and hs great potential) Perhps you could do a variety of ships.
Examples
Y-wing, B-wing, A-wing, V-wing, E-wing, Naboo Starfighter, Tie Fighter, Tie Bomber, Tie Hunter.
Throw some missles and bombes in there.
Sorry if I got into this, big star wars fan =P
Anyway, not bad. Good luck with your future projects.
