Delirium is 1st person, narrative, horror, short, rpg, action, limited interactive game where character has to search a house and unravel a horror mystery. The codes in game are difficult to find. Music and sounds exist as well as graphics are average. Short game. Reminds me of Evil dead 1. 5.35gb installation. Game works smoothly. Overall, I rate it ⭐⭐and half.
