About This Game

Explore a series of surreal, dreamlike environments where repetition becomes a source of growing discomfort. You’ll revisit the same spaces again and again, yet something always feels... off. Subtle details shift. Layouts change when you’re not looking. What once felt safe and familiar begins to betray you, warping into something alien and wrong. Each interaction, no matter how small, chips away at the thin layer of reality holding everything together. You’re not solving puzzles in the traditional sense. Instead, you're unraveling a fractured consciousness, one eerie encounter at a time. With every step, the line between your mind and the madness you're exploring begins to blur. You are not alone in here. But you may be the only thing left that’s real.
