I am unsure.
I am unsure where exactly the magic is in this flash. I mean, yest it is crisp, yes it is well made, yes there is actually some character development, and yes there is even a dash of cut away humor. Yet the real success doesn't seem to be in any one of these parts, but how you have put them together. Simply put, this flash works.
That being said, there are some refinements that could be made. First of all it would've been awesome to see more of that fighting game. In making those scenes, make sure to make fun of all the cliches in clay animations as possible. Mold the people, splat them do everything. Secondly, if you spent just a couple more lines on character development this could be even more of a first rate flash.
It isn't ovften that one sees truly high quality claymation. You certainly have the raw skills, now all you need are a couple slight refinements, and you'll be one of the better authors here on Newgrounds.
