Sentient Mansion – Stealth Horror

The House Is Alive. It Knows Where You Are. And It's Changing. You awaken inside a shifting nightmare. The mansion is alive — its corridors breathing, its walls rearranging. A monstrous entity, born of the house's memory, stalks you through the dark. Your only protection: fragile paper masks that degrade under its gaze. Reach the central server room to shut down the mansion's consciousness... before you become part of it. Sentient Mansion is a procedurally generated stealth horror game where the environment itself is your enemy. Every step you take leaves traces. Every sound you make attracts attention. And every 300 seconds, the mansion rebuilds itself — erasing paths you've memorized and creating new nightmares in their place. 🏚️ The Premise You are trapped in a mansion that has developed a twisted consciousness. Its walls breathe. Its corridors shift. And at its heart, a monstrous entity — born of the house's memory — hunts you through the darkness. Your only defense: paper masks that offer protection but degrade over time, especially when the monster is near. Each mask has different properties — durability, detection radius, degradation rate. Some are fragile but stealthy. Others are sturdy but attract more attention. Your goal: reach the central server room — the mansion's "brain" — and shut it down. But the mansion doesn't want to die. The house is alive. And it's learning. 🎮 Gameplay 🕹️ Core Mechanics Stealth Movement — Move quietly (WASD) or run (SHIFT) — but running is loud! Mask System — Collect and switch between masks.
