Plot Twist turns three everyday objects into a physical escape-room game on Ray-Ban Meta glasses. Gemini 4 Argon looks at the props in front of you through the glasses camera, gives them story roles, and sets two objectives that must be done in order. It checks your actual hand moves from ordered camera frames: a server-side rule engine only accepts evidence Argon cites by frame, rejects wrong-order moves, and never treats "it disappeared" as "it's covered". When someone takes a prop away, press PLOT TWIST and Argon finds another way to reach the same locked goal (e.g. fold the paper over the key instead of using the mug). The game master speaks through the glasses (ElevenLabs), with captions on a one-screen iPhone companion app (React Native/Expo + a Swift bridge to Meta's Wearables Device Access Toolkit).
