Continue Buttons?
First off, you should REALLY put how to watch IN the movie. Like (hit space to play) on the first frame or something. Not everyone reads full write-ups and for a bit there, I thought you forgot continue buttons.
The action was fairly good. I liked a lot of the effects you used. At times I couldn't tell if you used sprites for some of them or not.
Also, going back and forth from sprites to drawings was an interesting idea. I would say to draw a bit better next time, or at least more in the style of the sprites themselves (trace them or outline from them or something) because your drawings didn't really fit in so well, but it WAS a cool idea.
Some credits tunes would have been nice, too. =]
