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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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

Also, this game allows unrestricted live streaming and video uploads (including monetized ones) — no permission needed from us!

好玩好玩 对了 喵斯特莉亚是我妈妈
推理ゲーの中でもオカルトとSNSを題材として取り上げているので、プレイ感としては都市伝説解体センターや未解決事件は終わらせないといけないからなどを彷彿とさせます。 [spoiler] エレコちゃんかわいいですねえへへ[/spoiler] 難易度に関してはそこまで高いわけではなく、しっかり情報を整理していけばほとんどの人は解けるかと。 [spoiler] ヨウコさんもかわいいですねえへへ[/spoiler] 同作品をプレイしたことがあって、そういうのが好き!って方には是非お勧めします。 [spoiler] にゃすてりあちゃんかわいいですねふへへ[/spoiler] とても楽しく面白くプレイさせていただきました!
人物特定ゲームですが、納得感がありません。 指定の人物をSNSのタイムラインから引っ張ってくる形式ですが、なんら情報のないアカウントが多数あり、消去法で解く形になっています。 このゲーム内のSNSの参加者は事件に関係する数人だけのようです。そんなばかな。 あと主人公が気色悪いです。

とても素晴らしい作品...... 最近のTwitter(現X)ってマジでこんな感じだよなーという雰囲気が良く再現されています。 にゃすてりあちゃんに釣られて買いました。ヲタクはこういう子が大好き。 なんといっても推理が楽しい!他人のアカウント特定するのやめられん...... みんなも頭使いながらにゃすてりあちゃんを突っつこう! [spoiler]私はハピエン至上主義者なので後半の展開を身構えながら見守っていたのですが、トゥルーでハッピーな最高の結末にしてくれて本当にありがとうございます。幸せになってくれ......[/spoiler]
机皇严选
[h1]オカルトと美少女とSNSが好きなあなたへ[/h1] まさに、現代のSNS時代に生まれたゲームと言える。 ネット上でしか見ない、実際に会ったこともない人物の発言を真に受けて一喜一憂する。 複数アカウントを駆使してリアル生活から逃避する。 有名人が身近にいるように感じる。 様々な事件が発生し、消費され、忘れ去られる。 そして今日もSNSを見ながらSteamを起動するのだ。 [h1]既視感もあるが惹き込まれるゲーム内容[/h1] 題材としてはプレイしていて「あのゲームに似てるな」と度々思わなくもないが、オリジナリティもあり楽しめる。 総当たりでもクリアできる仕様ではあるが、やはりここはちゃんと推理をしていきたい。一発でクリアできると嬉しさも格別である。 主人公(プレイヤー)の性格に感情移入できないとツラいかもしれない。このあたりはSTEINS;GATEに近いかもしれない。 相棒である「箱内にゃすてりあ」は実に魅力的。基本的に会話劇なので、やり取りを楽しむことができた。 [h1]ラストについては賛否が出るか?[/h1] こういったゲームの評価基準は、やはりラスト、オチが一番大きい。 プレイヤーが納得できるかどうか。そういった意味では面白いオチだったが、その前の段階がやや冗長気味か? いわゆる考察のスキがない部分も惜しい。そのためプレイ後の感想が「にゃすてりあが可愛かった」だけになってしまう可能性もある。気がする。 それでも値段だけの価値は十分にあった。 約6時間で実績コンプ。購入時の参考にしていただければと思う。 次回作にも期待したい。良いゲームをありがとうございました。
[i]世界上永远充斥着未知。 然而在我出生之时,那些简单的事物早已被悉数解析清楚。 所以为了追求捕获真相的快感,才会用那些简单又低俗的事情找乐子。这就是我当网络侦探的真正动机。 所谓查明真相,不过是在自我满足。是一味规避风险、不敢走上前台的人所做的妥协。 真正有价值的不是查明真相,而是解决问题。光在网上敲敲键盘,其实就相当于什么也没做。[/i] 2026必玩推理新游。别名“开盒猫娘”,类型为轻科幻+社媒推理,在网络账号发布的帖子中寻找线索和真相。 至于帖子内容,那可真是包罗万象,啥都有,网暴、盗图、男女对立、宗教、福利姬、职场......从中能窥见不少近年的热门话题,顺带还neta了三次元的许多东西,描绘不可谓不栩栩如生,和“社媒”这一题材相得益彰。 毕竟网络世界就是这样,无奇不有,人性的阴暗面也好光明面也罢,网络不过是放大“人心”的载体罢了。“正如你有你的地狱,你所憎恨的人也同样深陷于各自的地狱之中。” 结尾惊天大饺子,但包饺子的手法亦有高下之分,像《Root Double》算是不错,但《谋杀谜案悖论 悠悠一夏十五载》则显得稀烂。毕竟饺子不能只让游戏中的角色满意,更重要的是让玩家也满意。从这点上来说本作无疑是大成功的。
面白かった。ヨウコさんかわいい!
整体难度不大,轻推理,本地化很厉害。 找关键词找线索还原故事的游戏挺多,但是像这样轻松愉快,故事讲得还有意思的少见。 真结局很好猜但是我很喜欢。非常推荐。 简单剧透一下吧, 第六章:混沌之子;第七章伪解答:彩虹牙刷(就连颜色都!)
Only finished the first chapter and I know I have to recommend this game You play as a cyber detective solving a mysterious crime case through exploring Twitte- Parrotter accounts. Finding keywords, connecting main and sub accounts of people, deducting motives, and connecting all the information you got to solve the mystery All of these play through the protagonist's PC screen I love how the game doesn't hold your hands in any bit. It just gives you some tutorials and let you try your hands on the game yourself, and the game's actually pretty challenging. It took me more than an hour to go through the first section of the game Edit: This game is one of the masterpieces I'd recommend everyone to try at least once. I will now sing praises for this game for another 5 years or more
