this is a very cool puzzle game. It took me a couple of goes to get the hang of it and then get into it, but once I did I kept looking forward to the next puzzle. It's got a great look and feel and I love the sound effects. The mechanic is really good too - I'm not sure if its completely novel but I haven't played this sort of puzzle before, so it was a lot of fun for me. Great job and well done. I hope you continue to work on it and release a full game - as someone else said it would work really well on mobile.
