Is there's more levels after the seventh one, you must debug...
1234 frames... I'm sure you can do with less frames for this type of game. No need to have nice graphics if it's static like that. The guy move is body in one block, laser are blocks, platforms are blocks... everythings blocks, solid, and it's poor in color. If it was more colorful, it'll may be a little more attractive.
You made something, but it can't expect more than this. 0 would say it's nothing, but it as at least something, so the least is 1. I given 2 because there's a gameplay, and there's music! But choose something else than windows themed music, it's... hm... I can't explain, sorry :/
It's not your first flash submission, so you're not a beginner in flash. But you got a long way to make. And if you're alone to make something, take all the time you need, or find some partners.
For my part... I have no knowledge, at least not enough to make something in flash ^^ But I tested a lot of flash games... but my life don't interest you, I think XD
May your next game be more interesting and attractive ^^
