Final Product: The Last Lighthouse — AVG Standard Framework
Cover
Game cover: The Last Lighthouse — generated by GPT Image 2 in 16:9: a lonely brick-built lighthouse on a rocky island at dusk, its beam sweeping over misty sea while the old keeper, the radio operator, and the diver stand on the cliff
Gameplay
Actual gameplay: the title screen — "The Last Lighthouse — island / unsent letter / three conversations", with the premise and Start New Game
Gameplay
Actual gameplay: the lamp room — "At the top of the tower only one dying rotating lamp remains. The old keeper has his back to you, clutching an unstamped letter." Progress, milestone, and speaker HUD visible
Gameplay
Actual gameplay: the first branch — ask who the letter is for, quietly stand beside him, or announce you came for the last shift. Every choice shifts Trust and Doubt
Gameplay
Actual gameplay: consequence of asking about the letter — the keeper does not answer at once, and something unreadable crosses his face as the weight of the air changes
Gameplay
Actual gameplay: free-input AI continuation — type "I ask whether the letter was ever sent" and the AI narrator writes the next beat, then offers three follow-up moves
The Last Lighthouse is a playable AI visual novel built on the AVG Standard Framework — the reference engine that powers every adventure game made in LEGO System Realms. The story is small and quiet: an island lighthouse about to be switched off forever, and three people who will not leave it — the old keeper with an unsent letter, the radio operator still listening to a dead channel, and the diver who has not finished searching the reef. You are the new keeper sent to take the final shift.
The AVG engine keeps the whole night honest: every line of dialogue is generated in real time, every typed action is parsed for intent — care, honesty, probing, teasing, pressure, observation — and every choice moves two meters: Trust and Doubt. Reach the truth too fast and no one confesses. Push too hard and the night closes.

Game Features
- AI-Written Story & Dialogue — Every line of The Last Lighthouse is written live by an LLM as you play: the keeper's guarded answers, the radio operator's dry jokes, the diver's evasions all stay in character, and the free-input box accepts any action you can type (deepseek-v4-flash real-time narrative).
- Free-Input Narrative Engine — The AVG Standard Framework's signature feature: instead of only picking options, you type your next move. An intent parser reads care / honest / probe / tease / press / observe, applies each character's traits, and the AI director writes the next beat — validated before it enters the story.
- Trust & Doubt Meters — Two meters from −9 to +9 track how the three residents open up or close down. Choices and typed intents shift them every turn, and milestone thresholds decide whether anyone ever tells you the truth.
- Three Conversations, One Night — The old keeper in the lamp room, the radio operator in the log room, and the diver on the sea balcony. Each refuses to leave for a different reason, and each only confesses it once you earn it.
- The LEGO System Realms Cast — Ten minifigures from the world — Brickley Vale, Lucy Spark, Sir Clutchlock, Nova Studd, Captain Redfin, Mei Gearheart, Sunny Bloom, Master Vitruvian Echo, Lord Permanox, and Glitchbit — appear as original full-body sprites, cut out to transparent PNGs in the world's stylized 3D toy-plastic look.
- Browser Playable — Runs directly in your browser, no download needed. Tap to advance, choose to commit, or type to improvise — restart any time to follow a different resident or a different path.

Production Process Breakdown
Stage 1: World Buildingclaude-opus-5
AI receives the creator's one-line world prompt "build a world that faithfully restores the LEGO setting — characters, locations, events, rules, and factions in the original art style" and generates the LEGO System Realms world — 30 atom cards: 10 characters, 8 locations, 3 events, 5 rules, and 4 factions. Each card carries an original description, cover art, and interconnections — including the Kragle Silence conflict that anchors the whole multiverse.

Stage 2: Game Design & Artgpt-image-2
AI designs the game from the atom cards: the AVG Standard Framework is configured for this story — cast, scenes, meters, intent rules, trait modifiers, and milestones — and all art is generated: the ten full-body minifigure sprites and the realm key art. Each sprite was generated on a clean background, then background-removed to a transparent PNG via BiRefNet.
