Patty's Oath — An AI-Built Verdigris Manor Mystery Roleplay (The Statement She Never Signed)
Final Product: Patty's Oath
Cover
The key-art cover: Patty stands full-front at the Verdigris Manor Record Table, a sealed statement in her own voice waiting under a green wax seal, a folded note half-slid beneath the sealed service door behind her. Painted in the world's canonical flat hand-drawn manor style with GPT Image 2 — thick ink lines, paper-doll proportions, a stage-still room, and the quiet feeling of being watched.
Gameplay
The live product, exactly as it opens at the share link: the title, the one-line premise ('Patty must decide whether to defend the certainty of her own signed account…'), the Act-as control set to Patty, and Start Adventure. This is where the player enters the roleplay — no install, no account needed to look.
Gameplay
Inside the manor's Study, played in the browser: the room card grid, the clue counter at 0/5, the narrator line — 'A page is missing from the ledger. The ash by the fireplace looks freshly swept.' — and Patty standing at the desk. Every circular hotspot is an investigable object, and every room can be walked with the arrows.
Gameplay
The Conservatory, mid-investigation: the pruning shears hotspot opens a narrator card — 'Wet soil is caught in the jaws, as if something was cut just moments ago.' — with Keep searching. Six rooms, 20+ clue objects, and an evidence log that fills as Patty's night is reconstructed.
Patty's Oath is a playable AI murder-dinner mystery set inside Verdigris Manor — a quiet, exacting character study wrapped around a forged statement, one missing minute, and a witness who obeys notes that carry Patty's name.
Patty speaks quietly, but every sentence lands like a notary seal. Tonight a statement bearing her seal appears on the Record Table, describing an action she does not remember taking. The paper is clean. The seal is perfect. One sentence uses a time reference Patty would never choose. Someone has been listening closely enough to counterfeit her certainty — and the Silent Witness has arrived to obey an order she never gave.
You act as Patty. Answer in your own words, or tap a suggested move, and a live AI agent writes the next beat, keeps every suspect in their own voice, and lets the physical evidence — the kitchen timer stopped a minute early, the fresh mark on the service-door latch, the note folded into the same narrow shape — challenge or confirm what you choose to say. Three investigable threads run beneath the dinner: The Statement Patty Never Signed (who can imitate her cadence but not her rules for recording time), The Missing Minute (why one minute beside the sealed service door cannot be accounted for) and What the Witness Owes (the old promise that made Patty's written word absolute). Each carries its own clues, actions, discoveries and consequences.
Beyond Patty's night, the manor keeps redrawing the wider case: every new run reshuffles victim, killer, weapon, crime room and hidden identity from the house's own pools. Interrogate, compare, plant a verbal trap, and submit a deduction before your actions run out. Play Patty's Oath →
Game Features
- Live LLM Narrative Direction — nothing here is a fixed script. A deepseek-v4-flash agent reads your action, keeps Patty quiet, exact and consequential, and writes the next beat, the subtext and the suggested moves as you play. It advances clues only in response to investigation, risk or deliberate conversation — and it never decides Patty's conclusions or loyalties for you.
- Patty's Voice Is the Whole Mechanism — the forgery works because it copies her cadence, not her rules. Patty makes every claim sound witnessed, avoids a particular time reference, and treats a sentence as a signed object. The AI holds that register exactly: no chat-assistant tone, no stray confession, every pause audible.
- Three Investigable Threads — The Statement Patty Never Signed, The Missing Minute and What the Witness Owes. Compare the forged page against her known manner of speaking; recreate the service route at the same pace; offer the witness a choice no written order could anticipate. Each thread has clues, actions, discoveries and consequences that change which ending you can reach.
- Answer In Your Own Words — Or Tap A Move — type any action into the free-text box, or pick a suggested move. Plant a deliberately unusual phrase and watch it reappear in the next forgery. Present two contradictory instructions bearing Patty's name. Defend the statement to keep control, expose her uncertainty, or turn the forgery back on its author before her word becomes evidence against her.
- A Case That Redraws Itself Every Run — eight suspects, eight weapons, six hidden identities and six investigable rooms are drawn fresh each run. The victim, killer, weapon, crime scene and secret change, so the same manor yields a different truth every time. Clues, interrogations and deduction choices decide when the pattern is finally visible.
- Painted Manor, Transparent Cast, Zero Install — the world's eight character portraits were cut out with birefnet-general into true transparent PNGs and composited over six painted room backgrounds. The whole mystery is a mobile-first browser page — free to start, nothing to download, and every room readable in dark or light.
Character Sprites
Sprite
Patty — the driver at the centre of the oath. She speaks quietly, and every sentence lands like a notary seal. Her certainty is the thing the forger is copying.
Sprite
Sabrina — the gardener. She speaks slowly, as if each word has been tested on the flat of a blade first.
Sprite
Lexia — she never avoids a question, but the sentence always changes shape before it reaches you.
Sprite
Reynard — he speaks like a man who has already read the transcript of this conversation.
Sprite
Neal — the chef. He jokes at the edge of panic, then looks surprised when the joke lands badly.
Sprite
Jonathan — the guard. He does not lie; he keeps his answers polished, factual and incomplete.
Sprite
Amayah — she observes before she speaks, and her compliments feel like measurements.
Sprite
Roland — careful, procedural, and always half a second too late to seem natural.
Production Process Breakdown
Stage 1: World Buildingdeepseek-v4-flash
The world "Verdigris-manor" set one canonical house style: flat hand-drawn comic illustration with early-2000s browser dress-up game bones, strict straight-on framing and paper-doll proportions. From a single world prompt the AI built the manor, its long-form murder-dinner premise, a suspect pool of eight, a weapon pool of eight, a hidden-identity pool of six, and 18 atoms — 8 people, 7 places and 3 lore entries — including the randomised case engine and the visual-style lock.

Stage 2: Roleplay & Story Draftingdeepseek-v4-flash
From the premise "Patty must decide whether to defend the certainty of her own signed account", the agent wrote the playable spine of Patty's Oath: the core conflict (an unseen correspondent manufacturing her voice), a three-way relationship graph, three investigable threads with clues, actions, discoveries and consequences, three locations (Kitchen Threshold, Sealed Service Door, Record Table), opening hooks, four story directions and a mission rule to never decide Patty's conclusions for the player.

Stage 3: Character Portrait Artgpt-image-2
Each of the eight suspects was painted as a 1254×1254 full-body front portrait with GPT Image 2, locking one consistent face and outfit across the world: Patty in a cream blouse and deep-green pencil skirt, Sabrina in gardener's linen, Neal in chef's whites, Jonathan in guard's uniform, and the rest of the dinner cast in the same muted mint, butter-yellow and garden-green palette.

Stage 4: Scene & Location Artgpt-image-2
The manor was painted room by room — Study, Billiards Room, Conservatory, Entrance Hall, Kitchen and Lounge — as straight-on, symmetrical stage sets with the lower third kept calm for dialogue. Each room carries one readable piece of wrongness: a torn ledger, a chalk smear, rinsed soil, an empty knife slot, a sunken cushion.

Scene Backgrounds
BG
The Study. A ledger is missing one page, and the ash near the fireplace looks as if it was recently swept. This is where the first version of Patty's night was written — and where the missing page still matters.
BG
The Billiards Room. A smear of chalk dust on the green baize feels like testimony left by one careless shot. A single chalk mark is enough to place a person here at the wrong hour.
BG
The Conservatory. Dark traces in the soil look freshly rinsed, and the leaf tips feel cold. Wet soil caught in the pruning shears suggests something was cut moments ago.
BG
The Entrance Hall. It is too empty, and any footstep would betray a person here. The perfect place to hear a door, a latch, or a note sliding under it.
BG
The Kitchen. The soup pot is still warm, and the knife rack has an empty slot like a missing tooth. The service route begins here, one minute before Patty remembers it.
BG
The Lounge. A sofa cushion is faintly sunken, as if someone has just risen from it. The room everyone passes through — and the one nobody admits to waiting in.
