Very nicely done, i really enjoyed it.
Awesome game, but I think the puzzles could be a bit harder. I could solve most of them in a few seconds.
The concept and execution are excellent, but I notice on the more complex puzzles that the physics can be noticeably different between multiple runs of the same unaltered setup. That's the only thing preventing me from a full five stars.
My computer crashed as there was to much going on to actually run the game. My computer never crashes so there is only one thing here that would make crash -_-
Well, that was fun. And mind twisting. And funny. And awesome. And Hairy. Pshht! ^^ 5/5!
