Don't accuse. Read the timeline until the truth is forced.
A Japanese SNS-puzzle deduction adventure in which you play the net detective El and solve supernatural murder cases using only the timeline of a fictional giant social network called Parrotter. You read posts for clues, gender, age, occupation, relationships, link public accounts to their secret alts, recover deleted data with passwords, cite the right posts as the grounds for your reasoning, and finally fit a hashtag to complete the deduction. It is OSINT-style investigation across nine stages, with no time limit and no game over: the core is your power to read, to filter signal from noise, and to think logically. Made by Japan's doujin indie team DigitalCats. It supports English, yet the wider West has barely found it.

01First, the one feeling
- All you are given is a timeline, and the case is buried inside the noise of ordinary posts, so the work is not chasing a culprit but reading: tracing gender, age, job, and who talks to whom until a face starts to surface out of the scroll.
- The click lands the moment a polished public account and a venomous secret alt turn out to be the same person, and you recover the deleted post that proves it, so the proof is not handed to you but assembled from fragments you chose to trust.
- There is no clock and no game over to rush you, so the pull is purely the itch to be right: you cite the exact posts as your grounds, fit the final hashtag, and the truth locks into place, and the next stage's timeline is already waiting to be read.
02Who this is for (and who it is not)
For you
- You love the Orwell idea of solving a case from someone's digital footprint alone, where deduction is reading public and leaked information and choosing which excerpts are the proof, rather than action or interrogation
- You want that core grafted onto a supernatural SNS murder mystery: link public accounts to secret alts, recover deleted data with passwords, cite posts as grounds, and fit a hashtag to lock each of nine stages, with no time limit and no game over
- You want a Japanese doujin-indie gem the wider West has barely noticed, Very Positive at 98 percent over 276 reviews, that already supports English
Not for you
- You want action, fast reflexes, or fail states; this is built around slow reading and logic with no time limit and no game over, so the thrill is being right, not being quick
- You dislike text-heavy investigation or want a big, already-popular Western title; this is reading-first, Japanese-led, paid at 1,300 yen, and still largely undiscovered abroad (about 7.6 percent of reviews are English)

Demons' Timeline Buried gem
A Japanese SNS-puzzle deduction adventure in which you play the net detective El and solve supernatural murder cases using only the timeline of a fictional giant social network called Parrotter. The criminals are superhuman beings called Akuma, and each paradox case is cracked by reading posts for clues, gender, age, occupation, relationships, then linking public accounts to their secret alt accounts, recovering deleted data with passwords, citing the right posts as the grounds for your reasoning, and finally fitting a hashtag to complete the deduction. It is OSINT-style investigation, nine stages in all, with no time limit and no game over: the core is your power to read, to filter signal from noise, and to think logically. Made by the Japanese doujin indie team DigitalCats and released April 2026. Very Positive at 276 reviews and 98 percent, yet with only about 21 English reviews (7.6 percent) the wider West has barely found it. It already supports English and Japanese, and at 1,300 yen it is a paid, fully released game.
Give it your first passOrwell: Keeping an Eye on You The origin
The origin of this taste: Orwell: Keeping an Eye on You, released in 2016 by Osmotic Studios and Daedalic Entertainment, put you behind a government surveillance system and let you read only a suspect's online traces, their social posts, chat logs, private files, and news, then drag fragments of conflicting evidence into a profile to decide who they are and what they did. By building deduction out of reading public and leaked information and choosing which excerpts to submit as proof, it defined the OSINT-style investigation adventure. Demons' Timeline is a clear heir to that idea: it hands you only the timeline of a fictional SNS and asks you to link public accounts to secret alts, cite posts as the grounds for your reasoning, and fit a hashtag to lock the truth, but it grafts that core onto a supernatural murder-mystery with deleted-data recovery and a nine-stage structure, making it its own creature rather than a clone.
