Gameplay
Actual gameplay: Shiratori Sarasa, the head maid, gives the first statement: “I have served in this manor for three years… Some rooms, I would not advise opening.”
Fog Manor is a playable interactive psych-suspense closed-circuit mystery game generated from the AVG-cases world in Neta Studio. Six strangers wake inside a Western manor sealed by heavy fog. The gramophone announces: one of you is the Wolf. By day you discuss and vote to exile one person; by night the Wolf kills. Find the Wolf and the front door opens — or die again and again in the loop, remember everything, and try once more.
Question the head maid, the discharged soldier, the doctor, the reporter and the tarot reader. Type any follow-up, accusation or observation and the AI director answers in the moment, while Trust, Suspicion and Insight meters track how every statement shifts the room. Six people. One Wolf. The only thing you can trust is the silence of the dead.

Game Features
- Live LLM Narrative — Every line of the gramophone’s decree, every suspect’s answer to your questions, is written live by an LLM as you play. Type a follow-up, an accusation, or an observation and the story responds in the moment — no two investigations of Fog Manor unfold the same (deepseek-v4-flash real-time narrative).
- Six Suspects, One Wolf — Closed-circuit social deduction: Shiratori Sarasa the head maid, Kuroki Teppei the discharged soldier, Haitani Shiori the doctor, Shion Akira the reporter, Kōzuki Eve the tarot reader — and you. By day you vote to exile; by night the Wolf kills. Find the Wolf, or loop forever.
- Trust · Suspicion · Insight Meters — Three live meters track the room: Trust measures who believes you, Suspicion how the pressure mounts against each suspect, Insight how much you have pieced together. Every statement and vote shifts them — and the Wolf lies too.
- Intent-Read Free Dialogue — Your freeform questions are read for intent: question, doubt, trust, observe, defend, accuse, or share. Each intent shifts the meters differently, and each suspect answers in their own voice — evasive, blunt, teasing, or cold.
- Full First-Round Script, Then Live AI — From Awakening · The Gramophone’s Decree to the First Vote and The Result Revealed: a complete scripted first round across six locations — Grand Hall, Dining Room, Library, Greenhouse, Tower Room, Voting Hall — before the live AI takes over.
- Browser Playable with Original BGM — Runs directly in your browser, no download needed. Save and continue, review the statement log, and listen to the manor’s own original soundtrack — title, discussion, suspicion and exile themes.
