Not bad
I love the concept of the flash. Great backgrounds, Terrific story, and the sound clips meshed in well :)
The only reason you didn't get a 10/10 was because I found with your style of stick figures when the arms overlap the bodies you cant really tell what the arms are doing anymore... perhaps a simple way to fix this is to add a black border around the arms when they go to overlap something of the same color? or perhaps making them just a couple shades brighter/darker than the body itself?
Anyway great flash! Can't wait to see more.
