Nice presentation, the pixel art looks fantastic. Not much of a fan of the 8-Bit music though. Gameplay is alright, but pretty frustrating at times. The healers are super annoying, because they heal each enemy every round and you can't effectively deal with them, because you are dependent on a good roll. If you don't get enough damage in like 2 rounds in a row, they are fully healed. Of course, this is complaining at a high level, so for a game jam game, it's pretty good!
On another note, I found a bug: if you jump while the transition between the two dices, you actually roll the first dice again and you can get a different number if you time it right.
