Interesting concept and very well polished execution!
I want to share just a couple of feedback on something that could be improved.
About the mechanics, I think they are well designed, but sometimes feels a bit too random (rolling dices, where upgrade spawns, where diamond spawns, shop choices...). I would prefer to have more control over at least one of those aspects.
The game flow is really cool, the complexity increase over time as the board expands. On the downside, because the numbers on dices do not increase, I felt like the outer loop took ages to be completed.
The game has good sounds, but I would like to have some background music help to set a mood.
Overall the game it's solid and engaging, well done! ^^
