First off... THE POST PROCESSING IS SO GOOD! It was WAY to easy, I beat it on my third try. You should have made some kind of attack at the back of the arena. Its well known along a lot of Bullet Hell game players, that pretty much any fight is easier the more distance between the boss. This was especially true with your game. The graphics were SO GOOD. I wish it was easier to see the boss health bar, because half of the time I didn't even know If I was doing damage. (But the white flash was a really good effect.) I also loved the mechanic of not moving to shoot, really cool idea. Great job!
