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
・Estimated playtime: 1–2 hours

Bought this while browsing a sale for detective games. The art style and UI immediately caught my eye so I decided to give it a try. 10/10 experience, absolutely worth the money. You play as a wannabe detective trying to solve a case by scrolling through a Twitter-like timeline to identify a person based on what they've posted. The story itself is also very interesting, but it's hard to say much more without spoiling it. Overall if you interested in short detective game with good story and like anime aesthetic. I really recommended. Bonus enjoyment point if you regularly browse JP twitter. This game really nailed the vibe perfectly
ビジュアルのキャッチーさや明らかにTwitterをモチーフにしたSNS「パロッター」を駆使してネット探偵をするという[b]「拙者たちがいつもやっていることではござらぬかww」[/b]となるライトな入りやすさから、想像もつかない終盤の引き込みがすごくて一気にクリアしました。 ミスリードだけに存在する情報がないのも好印象。 細かなパロディや時勢ネタも多く、SNSに張り付いてる人ほど楽しいはず。 最近のSNSに嫌気が差している人にぜひ遊んでみてほしいです。

完美结局就是好! 缺点就是剧情不够深(或者说玩的时候并不会有多大的情绪起伏,没有什么跌宕起伏的感觉大概) 玩完会有一种“原来如此”的感觉
good
うわー!!!めちゃくちゃよかったああ!! 情報整理もすごく面白いし、物語もとってもよかった!! メッセージ性も伝わってくるし、イラストもかわいいし、キャラクターもみんな個性的。 クリアした後に、うわああああプレイしてよかったああってなりました。 ちなみに、「Return of the Obra Dinn」に激はまりして、似た系統として紹介されてるゲームを下記の順にプレイ中。 「Return of the Obra Dinn」 「未解決事件は終わらせないといけないから」 「REPLICA(レプリカ)」 「Unheard ー罪の代弁ー」 「The Case of the Golden Idol: Complete Edition」 「ギャリー邸事件」 「Her Story」 どれも面白かったけど、好み的にはこの作品が一番満足度が高かったです。
まだ意外とレビュー少ないので早く圧倒的好評になるように 基本的にオブラディン系の推理というよりはStrange Holitectureとかのような整理に近いゲーム性 ただその手のゲームの中ではTwitter形式のタイムラインを確認して調査していくという仕組み上、調査阻害のための不要な情報もタイムラインとして楽しめる・それを通してキャラクターの輪郭もわかりやすくなるなど調査そのものも十分楽しいと思える出来になっている。 その上で個別チャプターではない全体シナリオの出来が素晴らしく、綺麗な物語の収束があり綺麗にまとまっているここ数年のADVでもかなり上位の出来だと思う。次作も期待しているのでぜひ頑張ってほしいです。
*******ネタバレ注意********** [spoiler]最後の最後で量子論だとか、観測して確定させたから過去が変わっただとか、結構曖昧で難しい話になった部分もあるけど、アクマが世界に起きたバグっていう部分は凄く腑に落ちた。本来その現象が起きた明確な理由は無くて単なるバグだった所に、エル(主人公)が(その事件に関わっていそうな)動機や証拠を観測し確定することで、あたかも犯人が自分の意志の下でその現象を起こしたかのように事件を確定させていただけ。 という理解で自分はかなりこのゲームの結末に満足してる。にゃすてりあが大量の国民の全情報を知ろうとした件も、自分の理解だとアクマの気まぐれ、世界のバグっていう事になっちゃうけど、これも勝手に確定させちゃってるだけなのかな?? この世界は”未知のもの”があるように出来てるって言ってたしな。そういうことなのだろう [/spoiler] 最後に、シュレディンガーの猫は観測者が箱の中身を見るまでは猫の生死が確定しないって理論だけど、箱の中から鳴き声が聞こえた、あるいは死臭がする、等々外的要因から可能性が絞られて行って、遂に箱の中身を見ずとも事実が確定する(確定させたことによって箱の中身が変わる)っていう新しい考え方が非常に面白いと感じた。
존나 재밌었다
面白かった。 AIに集めさせた情報を紐づけしただけて事件を解明したつもりになっている主人公を好きになれなかったが、 私自身もネットで得た情報で何かを知った気になりがちな人間であり、同族嫌悪なのだと気がついた。 [spoiler] 主人公がそれを自省し傍観者のスタンスを改めるところは身につまされるものがあった。 [/spoiler] [spoiler] エンディングが希望に満ちた形で締めくくられるのも、人の善性を信じよう、良い方向になるように行動しよう、という制作側から世の中への期待が感じられた。 [/spoiler] 私もそうありたい。
ゲームとして面白いし終盤も本当に素晴らしいと感じた
