My thoughts:
I came into this expecting a discount Dicey Dungeons. I was totally wrong. The dice being the only thing you use is an original and great gimmick. 9/10, may rnjesus bless thy. No 10/10 because enemy spawns can screw you over a lot.
I would love to see more special types of dice, like a "true" crystal dice that was OP, but can only be used once. Ever. Or a cursed mirror dice that swapped the value, making 1 to 6, 2 to 4, ect. It would make "the poop" useful sometimes.
