I had fun playing this one. Found I couldn't put it down till I got full upgrades. Only suggestion is the bullets are a bit hard to see with the stars moving close to the same speed in the back ground at around the same size and in the same direction...might consider slowing down the stars . Also something to notify you that you got hit by a bullet like a sound effect or make the ship flash white or something would have been nice but not really necessary once you got your ship fully decked out. Great submission!
