About Sanatorium
About Sanatorium
Sanatorium is a small 2D horror game with a Cthulhu-style theme, made by Milon. You wake in an abandoned sanatorium and explore its dark hallways with a flashlight. The game is a prototype and runs in the browser on itch.io. Its survival premise centers on finding a key upstairs and escaping before the creatures catch you. The listed tags include indie and pixel art.
Gameplay and choices in Sanatorium
In Sanatorium, the main decisions are how to move through the pitch-black hallways, where to point your flashlight, and how to reach the key to the main gate upstairs. The light helps you see, and creatures move more slowly in its beam. Batteries recharge the flashlight, so managing its use is part of the escape attempt. Movement and light are the main controls.
What sets Sanatorium apart
Sanatorium pairs a Cthulhu-style horror setting with a simple survival objective: search an abandoned sanatorium for the upstairs gate key and escape. Its flashlight gives the player a practical tool in the darkness, while creatures slow down when caught in its beam. That interaction adds a small tactical choice to the pursuit. It is a compact 2D prototype, rather than a broad RPG system with heroes or builds.
Is Sanatorium for you?
Sanatorium may suit players who enjoy dark fantasy and horror settings, tense escapes, and short sessions built around a clear objective. The flashlight and creature behavior offer a little tactical consideration during exploration. It is a Prototype. RPG fans looking for character classes, deep progression, or varied builds should look elsewhere.
