Very good.
It was good, it would have been nice if it were longer. I would suggest making the slowmotion part regular speed, it really didn't add to much to the flash and kinda killed the momentum. Also, make the loading numbers on the preloader a bit bigger. I thought the preloader was the actual movie for a bit and almost blammed it.
Good job over all though. And you're right. I do wish I were that good with sprites.
