Sure, let's outline the core mechanics first. Start with a locked room that opens only when a series of logical riddles are solved—each one revealing a clue that also doubles as a physical key. The twist? The final puzzle requires you to reconstruct a damaged blueprint of the room itself, so you have to use the parts you’ve gathered to deduce the layout. That forces a methodical mind to piece things together while the timer keeps the adrenaline pumping. Add a hidden hazard—like a pressure plate that triggers a brief blackout—to keep everyone on their toes. The real challenge is to balance the puzzle difficulty so it feels solvable but still demands careful attention.
