Rehna is a psychological horror quest for Android phones set in an atmosphere of travel, survival, and the search for answers in a hellish world within the labyrinths of the mind. The action takes place in a gloomy, dark place reminiscent of a psychiatric hospital, where a group of characters, resembling dolls or demons, meet. They are all sad and hopeless, mentioning in conversations a certain Rehna, who was of great significance to their existence but, according to them, left them some time ago. And like a hospital, the game gradually plunges into darkness, beyond which one can discern a seemingly endless wasteland and outer space. In this world, time seems to stand still and it is always night. As the game progresses, Gerinya will be immersed in an atmosphere of mysticism and horror, where every seemingly insignificant action will influence and change the world, like a puzzle. Where every dialogue has a special meaning, carrying with it a riddle and an answer. Faced with the incomprehensible and moving towards fears, you must find a way out and, with it, answers to your questions.
Rehna: Mental Hospital is the first in a series of mystical horror games about the psychological problems of young people, subpersonalities existing separately and forming a unified whole, inner demons and angels.
