That's a very clever puzzle with smooth animations!
At first I was afraid and tried to solve this fast enough because of cracks in the ice :D
Also, maybe it could be easier to play with camera at some angle. At least I could see 3 faces instead of 2.
Some levels had so many tiles that I just stopped guessing in my mind the first few tries to complete the level and just went at random. I just suggest that smaller levels are better for this game.
All in all, that's a solid puzzle game!
