Lost Sanity is a horror anthology where stories told by a group of teenagers on Halloween night come to life. Each tale becomes a playable chapter, revealing worlds that exist only between flickering candles, tense breaths, and the kind of imagination no one dares to admit is real. Here, every narrative is a door, and not all doors can be closed once opened.

In this art book, you'll get a behind-the-scenes look at the game's development, including the creation of its characters, environments, and much more. The book will be updated alongside the latest chapter of the game to avoid spoilers!

Part One - Call of the Sea: Concept art of characters such as Megan Claire, the Occultists, the teenagers, and places like the main house and the Occultists' cave.

Part Two - Coming Soon.
