About this game
Mnemosyne is an atmospheric psychological horror and anomaly hunting game that pushes your observation skills to their limits. You are trapped in a suffocating darkness that swallows you whole. This is an uncanny dungeon formed by stone walls, rusty pipes, and forgotten objects. You have only a flashlight providing limited visibility and a camera to record the truth. An Endless Loop, Altering Details You will find yourself stuck within a constantly repeating structure. While the architecture feels familiar, the details within mutate uncannily with every loop. Noticing the slightest change in your surroundings, displaced objects, or emerging oddities and successfully documenting them is the only key to breaking this cycle.

The feeling of isolation, the echo of your own footsteps, and the hostile demeanor of the environment will wear down your nerves. As you progress, the line between what is real and your delusions will begin to blur. FEATURES Suffocating Atmosphere: Navigate a near pitch-black environment with limited light sources. Experience intense isolation supported by immersive sound design and uncanny visuals. Dynamic Anomaly System: Test your attention with constantly changing, shifting, or morphing objects (props) within a fixed map layout. Memory & Observation: Use your flashlight and camera strategically to notice the finest details in your surroun…
