Immerse yourself in the chilling atmosphere of retro survival horror with chunky polygons, gritty textures, and moody lighting that harks back to the PS1 era. Feel the nostalgic dread as the low-res visuals bring a unique edge to the terror.



Encounter a mysterious humanoid creature that pursues, sabotages and adapts to your strategies. Outsmart, evade, and distract this nightmarish foe in a suspenseful game of cat-and-mouse where every move matters.



Take command of your ship operations including steering, engine maintenance, navigation, and resource management. Balance your focus between keeping the ship operational and dealing with the lurking horrors.



Experience a unique challenge every time you play with procedurally generated events and supernatural encounters. The ship’s layout, tasks, and the creature’s behavior adapt dynamically, ensuring no two journeys are ever the same.



Complete vital tasks under pressure to keep the ship functional. Solve puzzles, fix broken equipment, scavenge for supplies, and navigate through treacherous waters while evading the creature’s pursuit.

Survive the Stalker's Hunt

In Thalassomania, survival isn’t just about keeping the ship afloat—it's about outsmarting, evading, and surviving a relentless predator. Work together, stay silent, and navigate through your fear as you attempt to reach the safety of land. But remember, the creature is always watching, always hunting. Can you escape, outwit, and endure its clutches and find your way home?

Mature Content Description

The developers describe the content like this:

Since the graphics are retro, the extent in which they are graphic is limited, the creature that hunts you in this horror title will leave behind blood splatters and bodies will ragdoll, future plans for maybe adding more gore to certain rooms like a torture room but again the graphics will be retro so not overly gorey
