Whoa!!! I really enjoyed this. The player is a little slow but that changes the feel and tactics in it's own way so I didn't mind at all. Love the upgrades, the music was a good choice, the collision is fair and I was so happy when I won I played it again to beat my score which is something that never happens for me. I was proper zoning out towards the end there were so many bullets, it gets pretty trippy. Great job! I've forgotten what my high score was so I'm gonna play it again to check. :D
