Night Patrol of the Forbidden Forest is a playable interactive visual novel set in the Harry Potter wizarding world. Lights-out has long rung through Hogwarts. In the stone corridor, only torchlight and moonlight remain — and a faint blue-green magical residue creeping along the floor toward the edge of the Forbidden Forest.
You are Harry Potter, a first-year Gryffindor, with Hermione and Ron at your side. The story is written live as you play: investigate what the residue is, choose between reporting to a teacher, pressing deeper into the forest, or escorting your friends back — every decision shapes how the night ends.

Game Features
- Live LLM Narrative — Every scene, every reply, and every character is written in real time by an LLM as you play. No two night patrols pour out the same (deepseek-chat real-time narrative).
- Original-Premise Story — Strictly follows the spirit of the original: love, loyalty, courage and the pressure of school rules. No grand war or Horcrux arc.
- Branching Choices — Report the teacher, go deeper into the forest, or escort your friends back — every decision shifts the story and redraws the ending.
- Three-Character Cast — Harry, Hermione and Ron as first-year Gryffindors, each with multiple sprite expressions that react to the night.
- Handcrafted Sprites & Backgrounds — Full-body sprites cut out to transparent PNGs via BiRefNet; painterly dark-academia scenes with luminous spell light.

AVG Composite Frame — Gameplay Shotgpt-image-2
"Combine these exact references into one AVG screenshot; do not redesign any of them. Reference 1 is the full-body boy wizard character sprite — keep exact face, age, messy black hair, glasses, scar, Gryffindor robe and scarf, wand, full-body proportions; only place him standing in the lower-left third of the frame as a dialogue-scene sprite overlay, feet near ground. Reference 2 is the Forbidden Forest night path background — keep exact architecture of stone gate, tall trees, cyan magical residue on path, distant castle lights, palette and lighting as the full scene, unchanged. Reference 3 is the classic Japanese visual novel UI skin — keep exact warm wood border dialogue panel, nameplate style, soft cream text area, bottom overlay placement with blank text areas, classic VN toolbar language. Task: layout and lighting integration only into one finished visual novel dialogue screenshot. Soft moonlit integration so the character reads against the dark forest without redesigning clothes or face. No new character design, no new background elements, no restyling UI. Text: none. No watermark, no logo, no readable Chinese or English dialogue text."
