First of all, congratulations! This is one of the most interesting and original ideas I've seen, even compared to games with many more ratings (including ours maybe, haha), so great job!
My only suggestion would be to add a bit more UI feedback in the shop. For example, when you don't have enough resources to buy dice, the game doesn't provide much indication of why the purchase can't be completed. At first, I actually thought the shop was bugged before realizing I simply didn't have enough resources.
Overall, it's a very simple idea, but it's executed really well. Great work!
