This is shockingly good for a game jam game!
Really clever concept, easy-to-learn implementation, good difficulty of puzzles, interesting interactions of mechanics. The color palette is nice too. I was going to say the fantasy theme is a little bit unoriginal, but I actually think it helps this game by using something familiar/widely-understood to make the barrier to learning easier. I haven't yet seen any more classes beyond the Monk, but I intend to come back and see what else you've done with it.
Fantastic work!
