You play as L, a cyber detective investigating Paradoxes: strange incidents caused by people with supernatural abilities, known as Demons. With his Demon partner Nyasuteria, L searches for answers from his room, using information posted online rather than visiting crime scenes.
Each chapter centers on one or more timelines on the fictional social network Parrotter. Read posts, witness accounts, news items, and messages to identify who is behind public and hidden accounts, connect people to clues, and piece together what happened.
Point-and-click deduction tasks include recovering deleted posts with passwords and citing posts as evidence. Chapters build toward a final deduction using collected hashtags. Wrong answers can be retried, and hints are available; there are no time limits or game overs.
Players frequently enjoy piecing together account identities and clues from Parrotter’s timelines, describing the deduction as engaging and generally approachable, with hints helping when they get stuck. Many also praise the internet culture in the posts and the story’s closing payoff. Some find the timelines’ darker subjects unpleasant, while others criticize the pacing, character writing, or the deductions as too easy or not always conclusive.

Can you identify the culprit behind a supernatural murder using nothing but information from social media timelines—without ever leaving your room?
Humans with supernatural powers are known as “Demons”.
The bizarre incidents they cause are called “Paradoxes”.
Demons' Timeline is a mystery adventure game in which you investigate the truth behind these Paradoxes from the perspective of the Cyber Detective known as “L”.
Your partner, a Demon named Nyasuteria Hakouchi, assists your investigation with special abilities.
You will never visit a crime scene in the real world.
All clues exist online.
Using only information found on the internet, uncover the truth behind these strange and complex Paradoxes.
Players read through large amounts of information and solve deductions entirely through point-and-click interactions.
Each chapter features one or two timelines to investigate.
By analyzing witness statements, news posts, and social media messages, players complete multiple deduction tasks and gradually reveal the full picture behind each case.
Carefully read the information flowing through the timeline.
Deduce the owners of both public accounts and hidden alternate accounts, and connect them together.
Clues hidden within posts—such as age, gender, occupation, and relationships—help identify the people involved in the case.
Recover deleted data by discovering the correct restoration passwords.
Progress through the investigation by correctly quoting posts that serve as evidence for your deductions.
Use the hashtags obtained from the timeline to fill in the final deduction.
Complete the deduction and confirm the truth behind each case.
There are correct and incorrect answers during the investigation,
but there are no time limits and no game overs.
A hint system is available, allowing players to continue the story until the end.
