Pretty good looking game and quite fun to play although I couldn't get beyond the purple dices upgrade. And I found a glitch, if you have enough money for an item when opening the menu then buy an item you can keep buying and the gold will go negative. I tried that to see if it would give me an edge and it makes it a bit easier but it still feels like the roll cooldown is too slow.
A very nice entry for the jam, good job!
