Not too shabby, for stop-action
Would have been better in flash, but for the tools at your disposal you did a decent job with this. Granted, the frame-rate was a little slow. But, I'm sure it took an eternity just to get it this fast.
I know I could never garner the patience to put something like this together, so I commend you for that.
So for future submissions, pump up the frame-rate and try to add more of a plot. This was just a blob moving around, c'mon!
You have the tools to make something better, now use them!
