Nice game. Sound and graphics all went together perfectly. The gold ships were always turned around firing at the top of the screen. I was never sure what the green bar (green star pickups) was used for. I don't think there was an explanation other than on the resurrect screen that it called it PP. Because it was not full screen I did have one period of time where I didn't know why I wasn't shooting...my mouse fell outside of the game window. And when clicking outside the game window it paused...but then going back into the game, the ship was stuck at the bottom and could only move left-right but not up.
I had fun playing. Good submission.
