In "The Sleep Experiment" you play as a subject in one of the most disturbing experiments in human history. The game is a first-person horror experience, focusing on psychological horror and surreal imagery. You will navigate through a series of increasingly disturbing environments, each one designed to push you to the brink of insanity. You are kept awake for days, subjected to gruesome stimuli, and forced to confront your deepest fears and anxieties. As the days wear on, your mind begins to unravel, and you must face the creeping madness that threatens to consume you. Along the way, you will encounter other subjects who have succumbed to their madness, as well as the twisted scientists who are experimenting. Hold on to your sanity long enough to uncover the truth behind your inner demons and the experiment, or succumb to the madness that surrounds you!
