I know it was your first flash...
...so I'm willing to forgive things like the gigantic file size and even the poor voice acting and sound quality, but the flash seems to have a lack of animation. Even simple animation like walking and mouth movement is often missing. I can understand how walking animation is hard, but even people with no experience could draw an opening and closing circle on a person and call it a mouth. The lack of such is just laziness.
I'm sorry to tell you this, but the speed was horrible. This isn't a problem of there having to be a lot of explanation and dialouge cause that's fine. It's just that the animation in a scene took forever. The opening of the movie took too long (longer than the original), and the whole battle sequence took much longer than was necessary.
On the other hand, the art was great. I don't know if this whole business of you stealing it is true or not (although it would explain the lack of walking animation, just sayin...), but it's still good either way.
