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
・Save data can be carried over to the full version

8.3時間でエンディング・全実績 推理系のゲームだけど難易度もそこまで高くないしゲーム内ヒントもあるから推理系が苦手な人にもオススメ出来る。よくできたゲームで面白かった :) 微ネタバレ注意 [spoiler] エンディングのハッピーエンドへの結びつけが少し無理やり感はあったけどそれでもいいゲームなのは変わらない ;) [/spoiler]
I was terribly unlucky trying this after reading [spoiler]Chaos;Child[/spoiler]. Still would recommend.
SNSのタイムラインから人間関係を推察し、巷を賑わす怪事件の真相に迫っていく推理アドベンチャー。 ノーヒントトロコンまで6時間弱、程よい感じ。 最初から最後まで、なんとなく主人公は香ばしいかおりのする厨二引きこもr...安楽椅子探偵なので、初見でお口に合わない方はいるかも(作中でもその言動にしっかりツッコまれているところが個人的にはgood)、気になる方は体験版から推奨。 その他登場人物(SNSの住人含め)が良くも悪くも人間臭く、時には目を背けたくなるくらいドロドロとした感情や境遇に塗れていて、それが程よくSNS時代のリアルを反映していて魅力的。 道中割とキツめの内容のタイムラインがあるが、しっかり注意喚起されているのでヨシ! エンドロール・ED曲もとっても読後感よく見られたので、各キャラがお気に召したらぜひ最後まで読んでいただきたい。 表情豊かなにゃすてりあちゃんと人間関係の邪推をしてみてください、ニチャニチャと。 ネタバレ [spoiler]さすがに最終チャプターまで行くと、最後にどうしたら良いかはなんとなく分かるようになっていると思うが、真エンドにたどり着くまでに必ずIFエンド回収することになる。真エンドのために他エンド回収、という流れは昨今のゲームとしてはよくあるが、うまく設定を落とし込んでいるなぁと感心。各IFエンドのにゃすてりあちゃんともイチャイチャしたり追われたり共同生活(実家)したりしたかったぜ! [/spoiler] [spoiler] あと各エンドから主人公の本名が明らかになるけれど、タイムライン上のどこかで伏線あったかしら…見落としてるかもなぁ[/spoiler]

I was really surprised by this game! You scroll through a tweet timeline, piecing together the details of supernatural mysteries by linking main accounts to alt accounts and deciphering their identities with what information you can gather. As you do it you get to see into the online lives of different people and get to know the world's own little memes and internet culture, like the popular games and little references to things from years ago everyone just gets. It feels very authentic and recognisable if you've lived a life of internet scrolling. It's a cosy deduction game and not too difficult, but it has a lot of heart and a lot to say about the way we treat each other online, the personas people wear and the relationships we have with people we've only known from behind a screen. I loved the ending!
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
*******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。
不赖 小体量玩美了
偶然刷到的惊喜avg,推荐。 玩法是推特模拟器,根据TimeLine上的碎片情报匹配用户的大号小号、拼凑出事件的“真相”,过一把网络窥私、赛博断案的瘾。整体体量不大,每一关的攻略时间在半小时到一小时,总体文字量是比较大的,适合断断续续游玩。 剧情元素网罗了90年代悬疑小说的超自然杀人事件、00年代流行的量子力学和伪科学假说,1020年代的sns、vr、vtuber、ai、(甚至性别大战),都是avg爱好者和冲浪高手喜闻乐见、耳熟能详的内容。更难能可贵的是作者没有停留在梗的堆砌,而是很认真地把标题里的“观测”、“不确定”融入了游戏元叙事,在圆上作品内设定的同时很自然地引出了对后真相时代的批判和思考,剧情完成度非常高。而且我特别喜欢这个结尾,并没有很粗暴的让你放下网络touch grass,只是用不确定叠加不确定,在相互干涉的涟漪中试图抓住一些真物。不过还是要打一下预防针,如果你是那种“必须要有一个凶手”的传统派读者,可能会对结局的处理有些微词。 硬要挑刺的话,限于体量音乐比较单调,和猫娘/ai也没做什么点击互动;以及相比一些老牌推理avg来说,插科打诨的部分还是不够有趣。8月要出中文版了,根据生肉来看没什么难翻译的网络用语,正常汉化的话体验应该不差,感兴趣的买就完事了。
タイムラインを基に、事件の真相を解明していく物語。 難易度は割とカジュアル寄り、分からない場合もヒントが用意されており、一般的な推理が出来るのであればヒントなしでも可能でした。 メモとかは無くても出来るレベルだったので軽い気持ちでプレイ出来ました。 物語の方向性としては、9割よくわからない状態で進んで、残り1割で全ての伏線を回収する系。 以下、最後までプレイした感想。多少のネタバレがあるので閲覧注意。 [spoiler] 「観測することで結果が変化する」、シュレーディンガーの猫や二重スリット実験のような量子力学の考え方をテーマにした作品だった。 エンディングは最近のゲームに多いハッピーエンド寄りの締め方で、理不尽な後味の悪さや強いモヤモヤ感は残らなかったのが良かった。 [/spoiler]
很不错的小品推理游戏,真相有些玄乎,但本身足够优秀的节奏大大提高了接受程度 [strike] 试图同时满足年上控和年下控吗哈基喵你这家伙 [/strike]
