I know this comment is very late, considering the game jam was in 2018, but this is a great game. The platforming to charms is pretty difficult but fun to get through, and the boss battles weren't impossibly hard.
Thanks! Difficulty is really hard to get right in jam games - you have basically no time for playtesting, and the only person testing the game (you) has so much practice that it's very easy to make things almost impossible for new players :)
I also have a question about the gameplay, sometimes if you look up and press attack and jump at the same time, the knight goes flying up to the top of the screen. I think someone mentioned this in the cart you posted on Lexaloffle as well.
