A cool map idea, which I think really leans into the puzzle box theme of the title. An added layer of rotating rooms is a really nice touch and I can see that being very fun at the table the first time the players do that. I also really enjoy the backstory to the adventure, very creative and one of my favourite elements. Makes the whole adventure have a bit of weight and interesting context to it. Text is clear and I like the cover includes the puzzle cube similar to the map. An awesome module! 🧩
