Pretty neat idea - I'd love to play a postjam version where the monk gets some powerups. Game looks really nice too.
One thing I really liked was the ability to pick up multiple enemies when they're in the same spot. Most likely a bug - but it was very statisfying to use :D
Balancing in such a short timeframe is tough but since the game itself works so well, I'll give some feedback for that:
-The arena feels a little small sometimes compared to how big the player and the enemies are. It got a little better when I noticed that the spikes don't hurt you but I don't know if that's intentional.
-The enemy spawn in the field and - for my liking a little too fast and close. The game promotes creating a path with your ability but the fast spawns can ruin that aspect. Maybe check how close the player is to a spawn to balance it out a little.
-The game got a lot easier when I just focused on smashing the skulls - barely moving my player. Maybe the monk is lazy but I think there should be some kind of punisher in place for lazy players like me. :)
Anyway: great entry!
