Great atmosphere, definitely a game that makes you think a little bit about spatial awareness. I find the music doesn't fit too well but it's easy to overlook.
I love the design, and the idea is something I had never seen before!
Little problem for me: my screen was too small for the the game, it did not fit to my screen and so I couldn't see the full window, only the center. Enough to play, but I couldn't see the bottom row where the dice could be rolled.
