Cool demo!

Here are some things I've found that I'm wondering about:
1. The spinning bolt animation seems a bit of place sometimes, when the head of the bolt is facing you it spins way faster than when it's not facing you. The animation also seems to be skipping frames randomly sometimes (perhaps a flash issue?). Perhaps give them different starting frames so they don't all jump up and down at the same time.
2. On level 1-3 where the spinning spiked poles are introduced, the right one is nudging sideways, one pixel to the right, each time the animation is looped.
3. On level 1-4, the two pair of spikes down in the first pits seem a bit off since one of them are inside the wall.
4. The bee death animation seems to be a bit "floaty". At first I thought it was supposed to be some parallax effect, maybe it is?

5. Are the sound effects yours? If yes, are they final? They seem to clip at the end, also the frequencies are a bit off on some of them.
6. Instant death is, at least to me, very frustrating. Especially when it's not really your fault. For example level 1-5 where you're going to jump over some pits halfway through, where there are some bees lurking. The don't come up letting me shoot them until I've jumped, and then it's too late, I'm already dead and have to start over from the beginning. Level 1-5 is as far as I've come due to this. It's too bad I'm not motivated more to continue, because I really like the game, but the frustration gets the best of me

Anyways, good luck with Bolt Blaster, looks like it can be a really nice platformer!
