Well done, one of the best games I have played so far.
I think you have worked well with sounds, everything from music, sound effects and the voice. I also think that controlling the space ship feels really good.
I found the last level very difficult (first I didn't understand that I had to get the missile to hit the meteors which I discovered by accident, and then once I knew I couldn't manage to do it again). This could also be that I am not so good at the game :D. Maybe there could be more or bigger meteors to make it a bit easier.
