This is so close to perfection!
I dislike stick figures, I really do. As soon as I see a stick figure I get the impression that the author is just trying to take shortcuts.
Yet you make it work so well, that tiny touch of hair (and the PANTS!) make such a difference! Not to mention that you have so many tiny details that make up for a great whole. I mean, I just noticed that when I keep the snail shell up in the air you actually added a tiny counter for it! That made me smile.
My ONLY criticism for this is that I wish the character had some flesh on those sticks, and something besides an empty loop as a head. Since you've already shown to us what great and fluid animation you can muster, surely this wouldn't be a problem.
That being said, I know there are plenty of people who enjoy the idea of stick figures, and as far as I'm concerned you are by far the best stick figure game author at this point in time.
There's plenty to do, the game's got style, but over all - this game is FUN - and that's where its real beauty lies.
Well done, sir. I feel my time playing this was very well spent, and I hope you feel your time creating it was as well.
