Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 3.44/day in the week to Aug 4 → 22.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,419 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Supported Languages: Japanese, English, Simplified Chinese
* An unofficial Korean language patch created by the community is available.
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.
Because of the large amount of information involved, the game offers a challenging detective experience that rewards careful reading, information filtering, and logical thinking.
A free demo is currently available, allowing you to play up to Chapter 1.
・Chapter 1 out of 7 total chapters

都市伝説解体センターが好きな人はこのゲームやったほうがいいと思う。 推理パートも面白いし、最後の終わり方もきれい。 それはそうと、お兄ちゃんの裏垢意味わかったときわらちゃった。
A nice, fun, but short mystery game that makes the most of its anime aesthetic. Nowhere near as difficult as its contemporaries (Obra Dinn, Roottrees, Golden Idol etc), but a lot more funnier, topical and wholesome. This is a good entry point into the mystery genre. For seasoned players, it's definitely one you can complete in a single playthrough. I took some breaks to eat so probably would've been closer to 7-8 hours total, without using hints. But its general social commentary is on point, with a beautiful ending There are a few QOL issues but nothing game breaking; spelling errors, and the BGM does get a little mundane that I had to switch it off, though this meant I missed the ending credits song. Assuming this was made by a solo dev, I want to congratulate them on a job well done, and will definitely keep an eye out on any future games they make!. 8/10
X(旧Twitter)を再現したかのようなSNSを「観測」し、そこに現れる噂や人々の本音、事実の断片から本アカ、裏アカと各人のプロフィール(本名、年齢、職業等)を「同期」させて、背後の人間関係を「確定」していくロジックパズル。 要は、ゲームシステムとしては「オブラ・ディン号」や「ギルド探偵団」、「ゴールデンアイドル」等と同じです。が、題材が現代的なので解き味は「都市伝説」っぽい感じ。猫可愛いですね、AI可愛いですねで作業感はほとんど感じませんでした。エンディングでは、それまでただのデータでしかなかった登場人物たちの「解決」後のポストが流れるのが意外にうれしく、やって良かったなあという気分になれるのがとてもよかった。
