El Refugio de la Puerta Redonda — A Cozy AI-Narrated AVG
Final Product: El Refugio de la Puerta Redonda
Cover
The 16:9 key-art cover generated by GPT Image 2: Ondina, the lake spirit, barefoot in the ankle-deep Lago Bajo at sunset, while the round troll door open in the rock spills warm firelight onto the boardwalk of reeds.
Gameplay
Live gameplay — the opening line, "El agua se queda quieta a la altura de tus tobillos…", as Ondina waits on the shore of the Lago Bajo.
Gameplay
Live gameplay — the three attention choices of the opening: "Mirar alrededor del lago", "Escuchar el murmullo del viento" and "Caminar sobre el lago, descalzo".
Gameplay
Live gameplay — further along the route, Ondina mid-blink as the walk turns toward the Sendero de Juncos, with the wind's murmur held in the dialogue box.
There is a lake so shallow you cross it barefoot, and at the end of the path a round door opens in the rock. Inside, the fire is lit and the wind comes in only to bring you a sweet memory.
El Refugio de la Puerta Redonda (The Round Door Refuge) is a cozy, AI-narrated interactive game set in the world of the same name. You play yourself — no name, no sheet, first person — coming back to the refuge the way you always do: across the ankle-deep Lago Bajo, along the leaning Sendero de Juncos, and through the round Puerta del Trol that has no lock. Ondina, the lake spirit, receives you barefoot by the hearth, and the only thing left to decide is how long you choose to stay.
Every line, every beat and every choice is written live by the LLM as you play, and it remembers what you notice. The decisions are gestures of attention — listen, look, ask, stay — and what the wind returns to you depends on how long you stop to listen. There is no inventory, no timer and no score: only a soft afternoon and three gentle endings.

Game Features
- Live LLM Narrative — Every line, every gesture and every choice is written live by the LLM narrator as you play. The deepseek-v4-flash narrator voices Ondina, the wind and the refuge itself, and remembers how long you stopped to listen.
- Play as Yourself — You are simply "you": no name, no character sheet, first person throughout. You arrive unhurried and with permission to do nothing, and your choices are gestures of attention, never of combat.
- Free-Text Input and Live Choices — Type your next action ("sit by the fire", "ask her about the door", "stay a while") or pick one of the choices the scene offers; the engine answers and the live writer redraws the beat around your words.
- Four Scenes, One Afternoon — A complete chapter from the Lago Bajo to the Sendero de Juncos, the Puerta del Trol and the Sala de la Lumbre, with around fifteen actions gated in order so the walk always unfolds the way the place is meant to be crossed.
- Three Soft Endings, No Fail State — Stay the whole afternoon, come back early, or wait until the wind falls silent. None of them is a loss; the only quiet defeat is never having stopped at all.
- Original Ambient Score — Two instrumental themes, "La Lumbre" and "El Viento", composed for the refuge and played softly under the dialogue — no voice, no noise, just the room.
