Your first day at Dungeon Divers Incorporated. The organization's purpose is to render derelict dungeons safe for use by adventurers, which means clearing out the traps that previous inhabitants installed before abandoning the place. The work is structured like a Minesweeper puzzle: identify where the booby traps are, neutralize them in the right order, and finish the job without triggering what you came to remove. Your tools are limited. Your wits are what the job actually runs on.
