It's been a while since I found such a well designed game made with Puzzlescript. The puzzle design is very enjoyable, some of the game mechanics were quite surprising (especially, when a game element has two different functions in the aftermath), so yup, a great entry for the Chess Jam! :) I wrote a little recommendation article about your game and also uploaded a playthrough video. <3 That was fun, thank you very much!
Best wishes,
Sebastian
