I love the concept of players being trapped in a shifting maze of rooms. The mechanics of moving from room to room also seemed fairly streamlined once I got my head around it.
The visuals and vibe are perfect for a harrowing trek through a liminal space. The image of the shopkeeper on the cover alone drew me in just like the players would be drawn into the shop!
A point for additional polish, I think bolding the reference to Return to Start at the bottom of page 3 would help folks find it more easily.
I think this module is an excellent 1-2 shot to nestle into Prospero’s Dream!
