South Park — Something Must Be Done is a playable AI visual novel set in the snowy Colorado town of South Park. A viral kids' trend has the adults in full moral-panic mode: the PTA wants a ban, Randy wants a town meeting, and Cartman wants to sell the banned stuff out of his backpack for triple. You play Stan Marsh — the group's grounded moral center — and you have one school day to keep your friends together long enough to stop the town from banning childhood itself.
The story moves from the bus stop to the school cafeteria, into the town-square mob, and out to the frozen quiet of Stark's Pond. Calm your friends down, call out the adults' hypocrisy, or ride the chaos — every line of dialogue is written live, and every move shifts three meters: Friendship, Panic, and Cartman Control. Push Friendship high and the boys come first. Feed the panic and the town burns. Play Cartman's game and he wins.

Game Features
- AI-Written Story & Dialogue — Every line of dialogue, every choice, and every beat of the Something Must Be Done story is written live by an LLM in the voice of the world's own event cards — Stan's grounded rants, Kyle's moral lectures, Cartman's profit schemes all in character (deepseek-v4-flash real-time narrative).
- Three Live Meters — Friendship, Panic, and Cartman Control tick up and down with every move you make. The HUD never lies: calm the boys down and Friendship climbs; feed the mob and Panic takes the town; follow Cartman's plan and Control hands him the win.
- Play as Stan Marsh — You are the group's relatively grounded leader, the one who voices the audience's moral center — until South Park knocks you flat. Freeform input lets you decide exactly what Stan says next.
- The South Park Cast — Stan, Kyle, Cartman, Kenny, Butters, and Randy Marsh appear with original full-body sprites — cut out to transparent PNGs — over scene backgrounds in the flat cut-out paper style of the world.
- Branching Endings — One school-day crisis, three ways it ends: Friends First, Cartman Wins, or Town on Fire. Replay shifts the dialogue, the choices, and the price of every panic.
- Browser Playable — Runs directly in your browser, no download needed. Tap to advance, choose to commit, or type your own move to see the AI run with it.

Production Process Breakdown
Stage 1: World Buildingclaude-opus-5

AI designs the game from the atom cards: writes the story rules around the moral panic, designs the scene flow from the bus stop to Stark's Pond, and generates all art — the snowy title key art, the five scene backgrounds, and the six full-body character sprites. Each sprite was generated with a full-body sprite prompt on a pure white background, then background-removed to a transparent PNG via BiRefNet.
