Great game !
The idea is unique, and very well done. The balance between the random of the dice and the strategic choices is on point.
The environment is very effective, though I'd have loved to see it with subtler lighting.
Some little problems I noticed : the ground tiling isn't perfect and I did see Unity's skybox sometimes. Also, once I arrived to roughly 3/4 of the max distance, it stopped going forward there was no obstacle anymore. I could just draw the dice.
Overall, I really enjoyed your game, with its refreshing concept and tight realization.
