Great fun!
I spent some time playing this, and I managed to finish the game, all 22 levels. Too bad there doesn't come anything special after you finished it, just getting all the totems seems to be enough. The only bug I found was that, when you hold your mouse button down (as mentioned before), every tile you move over switches place with the next one you touch, making it sometimes easy to score big combos.
Anyhow, great game!
