Stardew Valley — Joja After Hours: A Night-Shift Mystery AVG
Play Joja After Hours (闭店后的乔家) — a browser mystery AVG set in the Stardew Valley world. You are the night-shift stock clerk at Joja Supermarket; manager Morris hands you a contract and an inventory sheet with no barcode. Clue, nerve and town-standing meters shape three endings before dawn.
Final Product: Joja After Hours
Joja After Hours (闭店后的乔家) is a playable 5-round mystery AVG set in the Stardew Valley world. You are the night-shift stock clerk at Joja Supermarket, and the closing inventory sheet in your hands was not supposed to exist.
Under cold fluorescent light, manager Morris tests you with a contract while the aisles whisper: price tags rewritten overnight, an employee corridor with no names, a second list in the warehouse, and a closing broadcast that is not for customers. Clue, nerve and town-standing decide what happens before dawn.

Game Features
- Live LLM Narrative — Every scene, every reply and every ending is improvised in real time by a live language model as you play. Morris notices your choices, and no two night shifts at Joja unfold the same (deepseek real-time narrative).
- After-Hours Mystery — A five-round investigation through the closed supermarket: the promo aisle, the employee corridor, the warehouse, the checkout broadcast — each beat a small discovery with big consequences.
- Meter-Driven Choices — Clue, nerve and town-standing track every decision. More clues reveal what the inventory sheet really lists; nerve decides whether you dare continue; town-standing decides whose side you leave on.
- Three Endings — Carry the evidence out of the store, leave the evidence and protect yourself, or accept the night contract. Every run ends differently.
- Official Pixel Style — ConcernedApe-inspired 16-bit pixel art: cold fluorescent blues, Joja corporate signage and crisp pixel edges, generated by GPT Image 2 to match the Stardew Valley look.
- Browser Playable — Runs directly in your browser, no download needed. Local rules-driven chapters play instantly; live LLM dialogue lights up on every page turn.
Character Sprites
Production Process Breakdown
AI receives the prompt “创建一个完全还原星露谷物语设定和风格的世界” (build a world that faithfully recreates Stardew Valley) and generates the 星露谷 world — 38 atom cards: characters (17), locations (8), events (5), lore (4), factions (4). Each card contains original descriptions, cover art, and interconnections.
AI designs the game from atom cards: writes the 5-round rules, the clue/nerve/town-standing meter system and the scene flow, then generates the Joja supermarket night background and the Morris sprite states. Each sprite was generated with a full-body sprite prompt, then background-removed to transparent PNG via BiRefNet.
Game built and published with one click, instantly shareable online. A live LLM (deepseek) improvises dialogue in Morris’s voice and reacts to your choices as you play.
Scene Backgrounds
Asset Prompts
“Production visual novel scene background for a Stardew Valley fan AVG set inside a closed Joja supermarket at night. Wide 16:9 interior view from the front entrance: long empty aisles, blue Joja corporate signage without readable text, cold fluorescent ceiling lights, polished pale floor reflecting thin light, checkout lanes in the distance, a dark employee door and warehouse corridor at the far right, subtle unsettling stillness, grounded illustrated game background, clean composition, no characters, no UI, no words, no logos, leave the left third slightly darker and low-detail for title copy.”
“Full-body visual novel character sprite source image for AVG runtime. Morris, the Joja supermarket manager from Stardew Valley, standing upright in a natural neutral pose, entire body visible from head to shoes, centered with generous margin around hair, hands, clothing, and feet. Plain pure white matte background (#ffffff) for clean cutout; no scenery, no interior, no exterior, no decorative backdrop, no gradient, no shadowy environment, no checkerboard transparency pattern, no pixel grid, no fake transparent background. Corporate supermarket manager outfit: neat blue vest over a white shirt, dark trousers, name badge without readable text, controlled professional posture, slightly tired middle-aged face, recognizable clean illustrated game style, consistent full-body proportions. No text, logo, watermark, frame, card border, or UI.”
“Create a reference-matched alternate full-body visual novel sprite for the same Morris character. Preserve the exact head shape, hair, outfit, vest pattern, body proportions, pose, camera, scale, margins, and plain white matte background from the reference. Change only the expression and tension: forced professional smile gone, eyebrows drawn together, eyes alert, jaw tight, one hand gripping the clipboard closer to his chest. Entire body visible, no cropping, no scenery, no text, no logo, no watermark, no border, no UI, plain white source background only.”
