It was weird in a good way, couldn't tell the difference between the birds I was controlling and the enemies at the beginning, and after a while I found I didn't need to move at all because there were so many bullets flying around I insta "killed" everything with one click. The movement was pretty enjoyable!

Its really hard to tell the difference between the player and the enemies, because they use the exact same sprites. Also, I think the enemies hit-boxes should be a bit bigger as they are very hard to hit.
