TRIANGLE LOOP — An Interactive Psychological Horror Time-Loop Game
Final Product: TRIANGLE LOOP
Cover
Game cover — TRIANGLE LOOP, generated by GPT Image 2 in 16:9: Jess stands on the rusted deck of the abandoned ocean liner Aeolus, her overturned sailboat drifting through the fog and the glowing triangle of the loop at her feet. A storm that should not have come — and home that never existed.
Gameplay
Actual gameplay: the title screen — "TRIANGLE · You have been here before." An ordinary trip out to sea, a storm that should not have come, an empty ocean liner waiting for you in the fog.
Gameplay
Actual gameplay: the Florida harbor — Greg the skipper waves from his sailboat while the crew gathers. Your call: "Board, push Tommy out of mind" or "Pause on the gangway — why the dread?"
Gameplay
Actual gameplay: the Aeolus · Deck — wet rust and déjà vu. The empty liner already knows Jess's name, and every pinned clue tightens the loop.
TRIANGLE LOOP is a playable interactive psychological horror game generated from the AVG-cases world in Neta Studio. An ordinary trip out to sea. A storm that should not have come. An empty ocean liner, the Aeolus, waiting in the fog. You are Jess — and you will board it again and again, until you finally understand: whoever wants to go home must first kill everyone. And home never existed at all.
The morning light is grey. Your name is Jess. Your son Tommy — seven, autistic — presses a crayon into paper, again and again, as if pinning something down. The doorbell rings. It is Greg, and the boat trip he promised you is waiting: Greg the skipper, Victor the deckhand, the married couple Sally and Downey, and Heather along for the ride. The sea is calm. Too calm, almost.
Then the radio catches a woman's voice, broken and shaking — "...help me... someone is killing everyone" — before the signal cuts. The Aeolus rises out of the fog, and the blood on the mirror reads GO TO THEATER. Every line of the loop was written live by Neta Studio's AI director as the game was built: you reply in your own words, the story bends around your choices, and the four loop truths decide which Jess walks off this ship.

Game Features
- Live LLM Narrative — The entire loop is written by an AI director: the sea trip, the crew, the Aeolus, the mayday and the four loop truths were designed live by an LLM as the game was built, and every turn runs on Neta Studio's real-time AI pipeline (deepseek-v4-flash real-time narrative).
- Free-Judgment Play — No fixed script to tap through. Each beat you write your own judgment — observe, recall, warn, confront, trust or refuse — and the fog answers. The same scene plays differently depending on whether you warn the crew or watch them walk into it again.
- Loop Truths & Rule Marks — The ship hands you four truths to test across loops: 1·Mayday is Sally, 2·Go to the theater, 3·More than one you, 4·Kill all to reset. Mark each unknown, true, false or suspect as evidence pins into your loop notes.
- Clarity & Crew Trust Meters — Every judgment shifts Clarity and the trust meters of Greg, Sally, Victor and Downey. Keep Clarity high enough to see the pattern — and keep the crew trusting you, or they will not listen when you scream at them to run.
- 12 Mood-Variant Character Sprites — Six characters with live expression states: Jess in dread, hollow, masked and resolve; Greg warm and grim; Sally soft and afraid; Victor flat and menacing; Downey nervous; and the masked shooter who waits on the upper deck.
- Cinematic Scenes & Multiple Endings — Eleven full-frame scene backgrounds — the grey morning home, the Florida dock, the sailboat, the capsized storm, the Aeolus deck, dining hall, cabin corridor, theater, crab beach and the road — and four endings to unlock, from The Next Boat to You Know the Pattern. Browser playable, no download.
Character Sprites
Sprite
Jess — the protagonist: soaked grey tank and jeans, a mother who keeps waking into the same grey morning. Four live moods: dread, hollow, masked, resolve (transparent PNG)
Sprite
Greg — the skipper: navy polo and boat shoes, warm when he waves from the dock, grim when the radio goes dead (transparent PNG)
Sprite
Sally — the old friend: soft when the sun is out, afraid when the fog rolls in. The mayday on the radio came from her — much later (transparent PNG)
Sprite
Victor — the deckhand with the wound across his forehead: a scar Jess gave him herself, in another loop (transparent PNG)
Sprite
Downey — nervous hands, worn flannel: the first to point at the still silhouette standing up high on the Aeolus (transparent PNG)
Sprite
The masked one — hooded, featureless, a rifle in hand. The killer stalking the corridors of the Aeolus... is Jess (transparent PNG)

AI receives a one-line seed prompt and generates the AVG-cases world — a studio library of interactive game cases. TRIANGLE LOOP was built from a single premise: an ordinary day out to sea, a storm that should not have come, an empty ocean liner in the fog — a psychological horror loop where Jess must kill everyone to go home, and home never existed.

Stage 2: Game Design & Artgpt-image-2
AI designs the game from that premise: the six-person crew, the four loop truths, the Clarity and crew-trust meters, the free-judgment input engine and the branching ending set — plus every piece of art: 16:9 cover key art, 11 full-frame scene backgrounds, and 6 full-body character sprites with 12 mood expressions, generated on plain backgrounds and cut to transparent PNGs.

Scene Backgrounds
BG
The Aeolus — the derelict liner rising out of the fog after the storm capsizes the sailboat. It has been waiting for Jess for a very long time.
BG
The Florida dock, bleached white with sun — where Greg smiles like a man with nothing wrong in his life. Six board the sailboat; the sea is calm. Too calm, almost.
BG
Storm · Capsize — the sea turns on the sailboat and Heather is swept away. Five survivors cling to the overturned hull as the Aeolus looms through the rain.
BG
Aeolus · Deck — wet rust and the smell of old iron. You call out; no answer. Your feet already know the way to the dining hall.
BG
Ship Dining Hall — the long table is set, steam still rising, as if someone just left. Turn back later and the food has rotted for days.
BG
The Theater — the empty stage beneath a single spotlight, where the blood on the mirror sends you: GO TO THEATER.

16:9 Cover Promptgpt-image-2
"Key-art game cover for TRIANGLE LOOP, an interactive psychological horror time-loop game (AVG-cases world). Cinematic photoreal, 16:9. A lone pale young woman with wet dark hair and a grey tank top stands on the rain-washed rusted deck of an abandoned ocean liner, seen from behind at three-quarter angle, fog swirling around her ankles; far ahead through the fog drifts her overturned white sailboat on an unnaturally flat, still sea. Behind her, towering through the mist, the enormous empty silhouette of a derelict passenger liner (the Aeolus) looms, a single sickly window glowing amber. A faint geometric triangle of light is reflected in the wet deck at her feet. Muted steel-blue, teal and grey palette, cold pale fog, film grain, dramatic chiaroscuro, dread and inevitability, no text, no logo, no watermark."
