Amusing bug:
Let's say I have a yellow die and a red die. I can switch the order of those two dice indefinitely. Not only does this scroll the dice off to the right, but it also increases my stats.
This works with any color except white as long as you have a yellow die and a die of that color. White dice sort of disappear if you rearrange them. I think you might be able to do it with two dice of the same color, but I only tried with yellows. If you have a yellow, red, and green, then you automatically win that round: you can hit the enemy's face without fail.
I won using the bug on my first try. Really fun game, bug or no. I had a basic hatchet (4 speed, 4 attack) for most of the run, and I wished I had stumbled onto something better. And that's probably my only complaint: loot drops seem totally random. I think I'd enjoy being able to choose between two enemies on each pre-demon stage, seeing in advance what (or at least how many) items I'd get.
