Lurking in Tenebris is a psychological horror game where you participate in a mysterious drug experiment, forced to escape mazes that intensify with every pill you take.

You’ve accepted a mysterious job from a random person, agreeing to participate in a scientific drug trial in an abandoned facility deep in the forest. Your task? Navigate through three mazes while testing substances that distort your perception and impair your abilities. Each pill you take brings you a step closer to the truth, blurring the line between reality and hallucination.
With each pill, the mazes become more dangerous and your perception less reliable. You’ll feel the weight of isolation and paranoia as the environment twists and turns around you. The facility holds secrets, and the environment is willing to threaten you. Can you uncover the purpose of this experiment, or will you lose yourself in the darkness?
It's not just regular thinking required for your survival; good listening-skills are a must too. The substances you’re testing alter your perception, making every sound a potential warning or a cruel trick of the mind. Hallucinations creep into your senses, intensifying the risk of panic and even heart failure. Randomly placed closets and ladders offer brief respite.
It is recommended to play at max settings, post-processing and headphones for the best experience!
This game was made by one person and without the use of AI, it may appear short, but I will expand it with updates in the future.
