Once again you astound me!
Damn that was a nice flash! It had everything you could want in such a short movie.
One small thing: the little squeak-sound felt spammed after a while, it'd be nice if you'd put different ones to each character (like, changing the tone of them for example). Maybe it was your intention of having it like this because of its simplicity, but I think it would rock. It'd give the individual characters more feeling.
There's simply no words. Thanks for sharing this, mate.
