Lost Sanity: Cthulhu is a horror and exploration game where each chapter is a new story. A group of teenagers get together to tell horror stories, and each story is represented as a chapter of "Lost Sanity." Starting with the tale of "Cthulhu," a cosmic entity that lies dormant in their city submerged in the sea, occultists gather with the goal of awakening the entity. You play as Megan Claire, a former reporter, who wakes up in a prison-like place. Your goal is to understand what is happening there and escape as quickly as possible!
