[@MatthiasAngel] Oh alrighty then. So, how about we take your idea of a building with multiple rooms and add a little bit of a spin to it?: The "building" is actually the inside of a video game, with the multiple various puzzles being levels inside. Some examples I can think of could be a dungeon crawling maze puzzle akin to Etrian Odyssey, and another one is general knowledge trivia questions? (kinda iffy on that last one though, because internet exists, obviously) I could probably think of more, but none come to mind atm.
