このゲームについて

"An ordinary report turns into a nightmare with a door opening at the bottom of a cliff."

You are a police officer.
On a stormy night, you respond to a routine call — but a sudden collision, a flipped car, and a fall off a cliff change everything.
You survive, but you don’t escape.
Before you lies a pitch-black cave, calling to you like the void itself. Inside — a single door.
Beyond the door — a cursed house.
The door shuts behind you, the house breathes, and the demon’s game begins.

Your mission is to identify and document anomalies — distortions in reality — within the house, and complete the ritual that will shatter the demon’s spell.
Each correct report brings you closer to freedom; each mistake feeds the demon’s wrath and twists the house further against you.
In the end, you will either break the curse — or remain as a whisper in the memory of the house.

Gameplay Overview

• Explore & Survive:
  A two-story mansion filled with hidden passages, locked rooms, and places that seem safe… but never truly are.

• Anomaly Hunt:
  Visual distortions, shadow figures, object displacement, audio interference, time slips, photo/mirror warping…

• Report & Progress:
  Gather evidence, document the anomaly, and report it correctly to advance the ritual. False reports attract the demon’s attention, raising both risk and tension.

• The Demon’s Game:
  The house reacts to your actions — the more you interfere, the more hostile it becomes.

• Final Journey:
  Solve all anomalies, complete the sigils of the ritual, and face the demon.

Core Features

• Psychological Horror & Atmosphere
  Even silence has weight: droning hums, shifting footsteps, breaths behind closed doors.
  Sight, light, and sound form the three pillars of tension.

• Dynamic Anomaly System
  Every playthrough randomizes the type, frequency, and location of anomalies — keeping you off balance and ensuring replayability.

• Investigation & Reporting Loop
  Observe what you see, gather evidence (notes, photo tagging system, audio traces), and report.
  Correct reports unlock ritual milestones.

• Ritual & Progression
  Collect clues from the house’s past (letters, photos, personal items) → decipher glyphs/symbols → break seals.
  The game isn’t about escaping — it’s about confronting.

• Adaptive Threat System
  Noise, light exposure, or lingering too long in one area increases the house’s hostility.
  The longer you play, the more the pressure mounts.

• Balanced Pacing
  Quiet dread → exploration → first encounter → escalating pursuit → final ritual.
  Each stage builds emotionally and mechanically upon the last.

Examples of Anomalies

• Spatial Distortions:
  Furniture slightly shifted, doors duplicated, stair rails changing direction.

• Static Entities:
  A motionless silhouette in a corner, a figure frozen beneath the stairs, a face staring unblinkingly.

• Corrupted Objects:
  An oversized chair stretching to the ceiling, a lamp that elongates unnaturally, a doorknob that shrinks into your palm.

• Extra Objects:
  A second window where there should be one, an extra glass on the table, an additional pair of shoes in the corner.

• Distorted Sounds:
  Half-cut whispers, repeating laughter that fades each time, a melody playing backward.

Each must be identified, evidenced, and categorized properly to progress.

Story & Theme

This isn’t just a haunted house — it’s a place that remembers.
The mystery behind the call that brought you here intertwines with a personal past buried within the mansion’s walls.

The question is:
“Was it really the demon that called you here… or the emptiness inside your own past?”

The answer lies within your reports.

Why Play?

Because this game relies not on jump scares, but on expectation, silence, and psychological dread.
Because every session offers new anomalies, evoking obsession through investigation.
Because the “Find, Prove, Report, Break” loop delivers clear goals and a deeply satisfying resolution.
