Thank you so much! If I had my way, I’d make one set that came with the Lobby, two Cell Doors, a Garbage Chute module, and the Endless Void module; a separate set that came with the Hallway module, the Endless Void module, four Cell doors, and a Garbage Chute module; and a third set with just a Cell. That way, people could easily buy however many they want of each unit to customize their setup without having to order pieces and the redundancy of extra modules is minimized.
