Honestly though, I'm not sure how the dice have anything to do with the upgrades you get, the only randomness I see is the upgrades offered when you have killed enough little amogi.

Yeah the game doesn't make it very clear but the dice actually enhance any card you pick. Was supposed to be a bit more of a complex system but we had to tone it down. But other than that everything is procedurally generated (such as the spawn manager using points to select random enemies etc) so the game is pretty random
