Final Product: Hogwarts: Before Midnight
Cover
The 16:9 key art: a young wizard in the candlelit Great Hall holding the sealed letter, the raven on its lantern beside him, the silver spiral adrift and the clock already past eleven.
Gameplay
Live gameplay: the opening scene in the Great Hall — the raven drops from the candlelight and lands on the table with a black-wax letter tied to its leg. Choice menu and the live narrator both on screen.
Gameplay
Live gameplay: the professor on duty reads the symbol — “The Keeper’s Mark” — and the clock is already half past ten. Three choices: 01 Search the library · 02 Follow the symbol now · 03 Study the map.
Gameplay
Live gameplay: following the symbol runs the story to the fourth landing and a corridor that has no business being on the map — a colour-wash location with three fresh branches.
A cinematic, choice-driven wizarding mystery you play in the browser — a raven delivers a sealed letter, something ancient is hidden beneath Hogwarts, and you have until midnight to find it.
Hogwarts: Before Midnight is a browser-playable adventure built on one night inside a living castle. You are a young Hogwarts student crossing the nearly empty Great Hall when a raven lands in front of you with a black-wax letter addressed to no one: “Something has been hidden beneath the castle. Someone is looking for it. You have until midnight to find it.” On the back is a spiral of seven marks, and the castle is quieter than it should be. The trail runs through the Great Hall, the library, a corridor that should not exist, the Forbidden Forest and down into a hidden chamber — and it ends differently depending on who you trust and what you are willing to become by midnight.
Every stop is a decision: who to ask, which path to take, which clue to chase, which creature to trust. Clues are remembered, favours are owed, and symbols start to make sense — while the clock never stops. The living LLM narrator writes each beat as you play, with fully authored prose as the fallback on every route, and the night resolves into three distinct endings — heroic, mysterious, and unexpected. AI enabled right in your browser, no download, no setup.

Game Features
- Live LLM Narrative — Every page, aside and reluctant admission is written live by the LLM narrator as you play. The deepseek-v4-flash narrator voices the Raven, the professor, the Librarian’s night desk and the Seeker’s absence — and carries your choices forward across the whole night.
- A Castle That Remembers — Under the story runs a quiet flag ledger: clues collected, trusts earned, paths opened, favours owed. Come to the professor early and they remember; break a creature’s trust in the forest and the chamber knows. Progress is saved to your browser, so the night is still yours when you come back.
- Twenty Decision Beats, Five Locations — The Great Hall → the library → the secret corridor → the Forbidden Forest → the hidden chamber. Roughly twenty decision beats connect them, and the route you take changes what each later stop will let you do.
- Three Distinct Endings — Trust the professor and gather every clue for the heroic end; keep the raven’s counsel and the symbol’s secret for the mysterious end; defy both and follow the letter literally for the unexpected one. Your trust choices, not a score, decide which midnight you get.
- The Keeper’s Mark & the Midnight Clock — A running clock gives every scene its pressure — “half past ten”, “an hour and a half” — and the silver spiral of seven marks on the letter is the thread that ties the library, the corridor and the chamber together.
- The Author Voice Is Built In — The Raven is the one constant presence on stage across every quest and branch: it speaks in short, precise sentences, knows far more than a bird should, and its true nature only pays off at the endings.
- Browser Playable, Touch-First — Runs directly in your browser with no download and no build, letterboxed for any screen, with every scene, choice and the type-your-own-action box visible and tappable on mobile.

Production Process Breakdown
Stage 1: World Buildingclaude-opus-5
From a one-line seed the AI builds the night of the letter: an original Hogwarts mystery with a raven guide, a professor who fears the symbol, a Librarian who trades answers, forest creatures that remember your kindness, and a Seeker already inside the walls. Five locations, roughly twenty decision beats, a running clock and three endings are designed and written as one connected night.

Concept Screen Mockup Promptgpt-image-2
"Create a polished visual-novel / AVG game screen mockup, 16:9, centered composition. Frame layout: a slim rounded pill-shaped top toolbar dock floating at the top center with a few small circular control icons (back, save, menu, settings, mute, network), plus one small folded-map icon. One full-body character standing centered in the frame: a young student wizard about fifteen, tousled dark hair, dark school robes with a crimson scarf, holding an open letter in both hands, expression curious and determined — in cinematic semi-realistic painterly storybook style. A full-bleed scene background behind the character: the grand entrance hall of an ancient wizarding castle at night — long candlelit tables, hundreds of candles floating in mid-air, an enchanted ceiling showing a deep starry sky, towering gothic arches of old stone, warm golden candlelight against deep blue night, faint golden magical particles drifting. Near the bottom: three rounded choice buttons … below them a wide rounded dialogue box … reading 'Something has been hidden beneath the castle. Someone is looking for it. You have until midnight to find it.' … Art style: cinematic magical-school aesthetic … No watermark, no logo, no border frame."
