Generated from: a scene from a small video game about: Create a 3D horror video game called “Black Academy: Castle of 70 Doors” [Horror Game Design] [Cinematic Horror Styling] [Horror Game Design] 🏰 SETTING The game takes place inside a massive, dark academy built like an ancient and mysterious castle. The building has dark hallways, abandoned classrooms, libraries, dormitories, basements, staircases, secret rooms, and doors numbered from 1 to 70. The main objective is to escape by passing through all 70 doors. Each door should lead to a different area and progressively increase the tension. The player must explore the rooms, search for objects, solve small puzzles, and avoid entities. 🚪 DOOR SYSTEM - There are exactly 70 main doors. - Each door has a visible number. - Some doors require keys, objects, or codes. - The final doors should be more difficult and dangerous. - The doors should have 3D animations when opening and closing. - Create ambient sounds: footsteps, knocks on walls, creaking doors, and other mysterious noises. - The player must be able to hide in closets, rooms, under tables, and other safe places. 👻 ENTITY 1 — SCARED Scared is a mysterious entity that can appear in approximately 10% of explorations. Unlike the other entities, Scared does not want to attack the player. - It has a strange but friendly personality. - When it finds the player, it asks for candy. - The player can give it candy. - If it receives the candy, Scared becomes happy, performs a short joyful animation, and disappears. - If the player doesn't have any candy, Scared may stare at them for a few seconds before disappearing. - Its appearance should be unexpected and create tension, even if it is not hostile. 🦠 ENTITY 2 — VIRUS [Image 1] Virus is the primary dangerous entity and can appear in approximately 80% of matches or areas where it is available. Virus is normally slow, approximately 20% of the player's speed, so it should not be extremely fast. However, when Virus appears: - The lights begin to flash. - Warning sounds are heard. - The player must quickly find a place to hide. - It can hide in closets, safe rooms, under certain furniture, or other hiding places. - Virus must roam the corridors looking for the player. - If Virus finds the player, it performs an attack animation. - The attack should remove approximately 30% of the player's HP. - After the attack, Virus can apply a poison effect that reduces approximately 3% of the player's HP gradually over a limited time. - The player should avoid directly confronting Virus and use the environment to survive. - Virus must have an AI capable of searching, patrolling, investigating noises, and checking certain areas. 🧸 ENTITY 3 — TOY BEAR Toy Bear is a huge 3D teddy bear. Although it looks like an adorable toy, it has an aggressive and unpredictable personality. - It is a special entity that can appear during exploration. - It can remain still as if it were just a plush toy. - It can suddenly change its behavior. - It can chase the player. - It must have animations for walking, running, looking at the player, and attacking. - Its movements should appear slightly strange to increase the terror. - Its appearance should contrast with its aggressive behavior. 🔐 DOOR 50 — THE GREAT CODE Upon reaching door 50, the player must enter a special room. The door will be locked and will display a message indicating that a code is needed. To open it: 1. The player must explore the entire room. 2. You must find different hidden clues. 3. The clues can be in books, on walls, desks, paintings, drawers, objects, and documents. 4. Some clues contain numbers. 5. The player must correctly combine the numbers to form the code. 6. The code must be generated variably so that it is not exactly the same in each game. 7. Upon entering the correct code, a cinematic animation begins where door 50 slowly unlocks. 8. After opening it, a new, much more dangerous section of the castle begins. 🎮 AI AND SURVIVAL The entities must use artificial intelligence to react to the player's behavior. Virus can: - Patrol. - Investigate sounds. - Search for the player. - Chase the player. - Lose the player if they manage to hide correctly. Scared must: - Search for candy. - React amicably when it receives candy. - Disappear after achieving it. Toy Bear must: - Patrol specific areas. - Remain motionless to deceive the player. - Be detected and pursued when he becomes aggressive. 🎥 CINEMATICS Add 3D cinematics when encountering each entity for the first time. Some scenes should utilize: - Third-person or cinematic camera. - Slow zooms. - Flickering lights. - Camera movements. - Facial and body animations. - Ambient sounds and horror music. 🎯 FINAL GOAL The objective is to survive and progress from door 1 to door 70. Each section should feel different, with new rooms, puzzles, events, objects, and encounters with entities. Door 70 should be the final exit from the castle and trigger a grand final cinematic when the player manages to escape. Create everything in 3D, with dark lighting, an abandoned academy atmosphere, a gothic castle, fog, dynamic shadows, ambient sounds, and a constant atmosphere of terror., as an in-game screenshot in flat colour 2D shapes with a bright limited palette.

Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one. Keep the pictures honest: they promise what a small first version of this game, made in a game engine in a few days, can look like. Simple readable shapes, clear silhouettes, few flat materials, the in-game camera view. Never film stills, photoreal renders, AAA key art, detailed textures, cinematic lighting, or anything that looks like a big-studio game. No text, UI, HUD, logos or editor screens inside any image.
