Star Tide Pact (星潮之约) is a playable rain-night fishing AVG set in the Stardew Valley world. You are the new farmer; before Joja breaks ground on the automated trawling pier, you and Abigail must land the legendary Star Tide Carp and decide who keeps the waterways of the valley.
The story runs across three days in order — a rainy beach, a forest lake, a midnight pier. Abigail can see the violet starlight on the fish shadows; Willy knows the old waterway pact; Morris speaks for Joja and its pier plan. Bond, waterway resonance and Joja pressure track every decision, and the ending under moonlight only opens when you have earned it.

Game Features
- Live LLM Narrative — Every scene, every reply and every ending is improvised in real time by a live language model as you fish. Abigail notices your choices and never fake-catches a fish; no two nights on the water unfold the same (deepseek real-time narrative).
- Three-Day Mystery — A structured run across three late-spring days: the rainy beach, the forest lake, the midnight pier. Advance exactly one concrete clue or character reaction per turn, never skipping or going back.
- Tactile Fishing Minigame — Key catches become an active challenge: hold to reel, release for slack. Catch progress, line tension and time left decide whether you land the fish or lose it, fishing records included.
- Three Meters, Three Endings — Bond, waterway resonance and Joja pressure track every choice. Push it all the way to the pact under moonlight, and the finale only unlocks when bond and resonance are high enough.
- Official Pixel Style — ConcernedApe-inspired 16-bit pixel art: deep sea teal, rain blue, weathered wood, lantern amber and amethyst accents, generated by GPT Image 2 to match the Stardew Valley look.
- Browser Playable — Runs directly in your browser, no download needed. Local rules pace the chapters instantly and live LLM dialogue lights up on every turn.

Stage 2: Game Design & Artgpt-image-2
AI designs the game from atom cards: the three-day fishing structure, the bond / waterway-resonance / Joja-pressure meter system and the scene flow, then generates the rainy beach, forest lake and midnight pier backgrounds, the star-tide title screen, and Abigail's four-expression sprite set. Each sprite was cut out to a transparent PNG via BiRefNet.
