It was fun and I liked it a lot but I my big things were make the ship get bigger when you upgrade and make the bullets more significantly bigger with each upgrade. If you were to make it sort of like starfighter disputed galaxy with the dif weapons and ships but keep the upgrade idea it would be the best ever.
