I want that music! :) Very catchy!
Those powerups were pretty tricky too. I think I would have liked to see some sort of visual indication on the ship itself when I got hit by a bullet or when a powerup effected me or when I died. Maybe the color of the ship changes with certain powerups, or there's a teeny explosion on the front of the ship when its hit, and when you die, a screen shake or some sort of death animation might make it feel more real and even more fun to play.
It was really fun to fly around with these controls and easy to get used to playing. Very nice entry, great job! :D
