Great game! Easy to understand concept and very clean visuals and audio.
I personaly felt like puzzles were a bit to easy to figure out. I wonder if this idea as is can be used to create something truly challenging, or perhaps there needs to be some extra mechanic to do so. For example level 6 would be way more challenging if the player was able to move the boxes around and had to place them at certain positions to stop the die rotation.
In any case - very enjoyable game and a creative interpretation of the theme.
