In a world where the rich and famous wear enchanted masks that grant them unique personas, you play as a mask-switching janitor in a sprawling, luxurious mansion owned by eccentric celebrities. When a priceless diamond goes missing during a masquerade party, you must navigate the absurdities of high society, interrogate the partygoers, and piece together clues while donning different masks yourself. Each mask changes your abilities, personality traits, and dialogue options, allowing you to experience different perspectives on the mystery. The more outrageous your choices, the closer you get to solving the crime—if you can survive the party's twisted secrets.
