Wow, definitely a unique game! Love the art direction and sound design.
The gameplay is also very cool! I think it's really hard (or maybe I'm just missing out on some mechanics), but that's a good thing since it encourages experimentation. One strategy I came to use was always having wood on stock with the minions, so they can be ready to repair as they are helping the witch brew. Given this strategy, I think it might be nice to have an indicator that a minion is already holding since I lose track sometimes.
One other mechanic that I thought could fit (but you might disagree) was maybe some way to heal? Or atleast regen. On one hand, the game gets very tense near the end where you have low health. But sometimes I messed up near the middle and get stuck with low health for the rest of the game.
But anyway, definitely one of the most unique gameplay I've seen in this jam! :D
