I'm Not Alone is a computer game whose plot focuses on Lilian Von Gruber's large and luxurious estate in the Alps, which is overrun by supernatural forces. The player takes on the role of an extremely brave and slightly eccentric exorcist, whose goal is to cleanse the property of these forces. Unfortunately, during the game it turns out that the monsters that have taken over this place are much stronger than anything the exorcist has dealt with so far. The character is characterized by special abilities such as moving between reality and the world of demons, and also has the ability to choose different types of weapons with which the player must send the monsters back to hell. The game is inspired by the classic of the genre, "Alone in the Dark" and does not allow the player to rest all the time in the horror room. Thanks to the numerous attacks of monsters and the skilful play of light and shadow play, as well as the changing position of the camera, we have the impression that we are in a real place. Realistic graphics emphasize the dark atmosphere of the game. There are also logical elements in the game, which fans of intellectual development should be satisfied with.
