About Sanatorium
What is Sanatorium?
Sanatorium is a small 2D horror game with a Cthulhu-inspired setting and pixel art. You wake in an abandoned sanatorium, where a flashlight is your only light. The game was made by Milon and is available to play in a browser on itch.io. It is listed as a prototype, so expect an early version rather than a finished, feature-packed release.
How a run of Sanatorium plays
You move through the dark hallways and use your mouse to aim the flashlight. Find the key to the main gate upstairs, then escape before the creatures catch you. Your flashlight’s batteries recharge, and monsters slow down when they enter its beam. The goal is clear: navigate the sanatorium, manage your light, locate the key, and get out. The available facts do not say what happens after an escape or whether there are multiple runs.
Why Sanatorium is worth a try
Sanatorium puts a flashlight at the center of its horror: its beam lights the halls, recharges with batteries, and slows monsters. That makes each glimpse useful when you are navigating a pitch-black building with creatures on your trail. Its abandoned sanatorium and Cthulhu-style horror give it a different mood from the monster collecting and upgrade chasing of Poke Survivor. If you came looking for a survivors-like, expect a compact escape focused on finding a key instead.
Who will enjoy Sanatorium
Sanatorium may suit players who want a short browser horror game with a clear escape goal, pixel art, and a tense flashlight mechanic. It is easy to understand what you are chasing: find the upstairs gate key and get away. Survivors-like fans should set their expectations accordingly; the given facts describe an escape from creatures, not collectible monsters, upgrades, or a between-run progression system. It is listed as a prototype, so the game is still an early build.
