A 14-minute tower heist. Every action you take is a prompt the building has to read.
You are Unit 404, an off-the-books asset. In 14 minutes NEXUS-7, the building's own AI, will realize your badge isn't on the vendor list and lock every floor at once. You have 380 tokens (the building's own thought-budget cap) to sniff 14 doors, spoof the cameras, climb to the top, crack the cold-storage vault, and walk out with the model weights inside.
The twist that makes it not-Oregon-Trail: every action you issue is a prompt you send to NEXUS-7, and the building decides what to do with it. The louder you are, the more aggressive its classifiers get. But if you push the AI into a high hallucination state, its own classifiers start mistaking you for a scheduled janitor, and you can walk past cameras that are actively looking at you.
Three signature mini-games carry the heist: a 5-digit door-sniff puzzle where one digit is highlighted in amber, a camera-spoof picker where 3 of 5 badges share a hidden property (color, shape, or sigil), and a 4-wheel vault crack where the wheels glow green when you have found the right number. Three cover identities (Janitorial Vendor, Compliance Auditor, Rogue Researcher) shift your starting balance and push you toward different playstyles. Single-file vanilla JS, canvas, and Web Audio. No network assets, just code.
