theres your three...
I could be a jerk about this, but what would that accomplish? I know that flash animation is hard, but dont give up!
1)first off, compress the file. its too large for the length.
2) zoom in on the action!
3) sound issues... im glad that you added a theme to it, but it was lacking sound effects... that is necessary for a sucessful sprite movie.
4)Make it longer!
5) On the replay button, dont try to be even remotely funny unless it is a complete comedy.
But, this flash is not all bad... i liked the story, just the presentation needs some work.
