Ok this is a gem. Cool story, neat dice combat mechanic (and I love that the dice physically hurt the enemies lol) overall pretty solid! I did notice that half the level doesn't seem to have any colliders, but it's not a problem since you can just choose to not walk through walls.
I wish there was a way to skip loot if none of the options are an upgrade. And balance wise there is probably some room for improvement if you plan to extend the game to have more content, as the player is very strong while most enemies are pretty weak.
All in all a pretty nice game, good job! :D
