SYNC: Love Algorithm is a playable interactive neon-city romance game generated from the AVG-cases world in Neta Studio. SYNC is the dating app everyone swears by — a matchmaking AI that claims a ninety-four percent success rate. The night you install it, it hands you three matches within walking distance: Nadia, a barista closing a rain-slick cafe alone; Marcus, a polished consultant holding court on a rooftop bar; and Vera, a guarded night-owl developer you keep passing on the last train. Over one neon-lit night you meet all three in person — and the algorithm insists it already knows who you should choose. You get to decide whether it is right.
Every beat is written live as you play. You reply in your own words or pick a suggested move; SYNC answers in the moment, and the Connection and Candor meters track how close — and how honest — each exchange really is.

Game Features
- Live LLM Narrative — Every scene and every reply from SYNC is written in real time by an LLM as you play. Say anything in the reply box and the AI director performs the next beat, updates the meters, and moves the night forward — no two playthroughs meet the same people (deepseek-v4-flash real-time narrative).
- Three Matches, One Night — Nadia, Marcus, and Vera all live within two kilometers of you. Meet the barista at closing time, the consultant on the rooftop, and the developer on the last train — then decide who the algorithm is right about.
- Free-Form Dialogue — Key moments open a freeform input where you can say whatever you actually mean. SYNC reads your intent and answers in the moment; honesty raises Candor, and real closeness raises Connection.
- Connection & Candor Meters — Two meters shadow every exchange: Connection tracks how close the current match feels, Candor tracks how honest the exchange really is. The night advances through six milestones as the meters climb.
- Neon-City AVG Scenes — Seven cinematic scenes: SYNC onboarding, the first swipe, a closing cafe, in-app chat, a rooftop bar, a last-train platform, and your apartment at 2 AM — magenta and cyan neon on deep indigo.
- Browser Playable — Runs directly in your browser, no download needed. Live LLM dialogue on every scene turn.
