Demons' Timeline is a mystical detective game where all investigations take place directly within timelines, news feeds, and internet messages. The player takes on the role of cyber detective "L" and attempts to unravel a series of strange murders and supernatural incidents without leaving their room. Instead of searching for fingerprints and exploring the streets, they must delve into other people's posts, compare accounts, and piece together a picture of events through digital traces. The main thing here is to read people carefully. Almost the entire investigation relies on information the characters themselves post online. Some accidentally reveal themselves in comments, others maintain hidden accounts, and still others delete important data in hopes of covering their tracks. The player must manually link profiles, analyze messages, and search for details that will help them understand who exactly is behind the latest "Paradox." During investigations, the demon partner Nyasuteria Hakouchi, with her abilities, assists, but the game still doesn't provide ready-made answers. Final conclusions must be drawn independently through discovered hashtags, quotes, and recovered data. Because of this, the game feels less like a typical visual novel and more like a full-fledged digital investigation, where almost any detail in your feed can suddenly become a key clue.
