I enjoyed this game! Thought it too me a bit to grasp the gameplay loop, I thought that it played really well into the main theme of the jam. The sprite work on the monsters and theme were on point, I especially enjoyed the vampire sprite which really gave me "Lavender Town" vibes.
I think if you were to keep working on this, adding some kind of visual aid to help the player understand the internal "dice" rolls could be helpful and make the actual "rolling" more satisfying.
