Thanks for playing, and thanks for the feedback! Good point about the bouncing projectiles, I'm not particularly happy with them. The idea was just to make the game easier since you are already dodging everything and maybe don't have time to focus and aim each shot. I frequently forget which way I'm facing, which is probably a bad sign since it's my own game...
For future people, I should add that you can skip to the next level by pressing 6. I personally feel that going back to the last checkpoint after running out of lives is the right design for a game like this, but the player absolutely has to WANT to replay the levels for that to work.
