I really like the vibe and the idea! I think I am usually pretty good at puzzles but this one really got me. As said below by Jamie Birch, I think a more incremental introduction would have been great, I really struggle to visualize the moves and having more practice with the mechanics would help ! I don't know if you had time to get someone to playtest it, but I think it would help making it easier to approch (in a jam setting).
Anyhow, I saw that you are planning a solution guide and I think that's a great idea! I look forward to that so I can try my hand at the game more :)
