At your response to sk8ting's comment. Are you sure talking shouldn't mean things AND stuff?
Anyway, you're overly humble about this game. It's quite good. A lot of shooters that get published feel as though the designer never actually played them. In this one, there are little touches that make it clear that you tested and edited, tested and edited. For example, the rash of new enemies at the beginning of each level is very nice to help you get accustomed to what you're going to be seeing. The keyboard response is nicely adjusted, neither too fast nor too slow, and meshes well with the speed of the enemies well - i.e. you can't match the up and down speed of the bouncing skulls, making it not too easy to kill them, but you can move faster than anything on screen, making it possible to outrun them.
I sort of agree with the last reviewer that a more dramatic destruction animation/sound combination is always satisfying, although I thought his suggestions were silly and would really harm the game experience. The puff of smoke is nice, but maybe a larger explosion, and a variety of enemy death sounds depending on the enemy. I think I noticed you did do that for the bosses.
Definitely the big thing missing here is powerups. Obstacles are also a nice addition to shooters, creating variety both by forcing the player to do two things at once and by providing an opportunity to unleash massive destruction on a line of enemies coming through a bottleneck.
Loved the hawt witch.
