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 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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

整体流程不长,推理过程轻度但基本环环相扣,完全没有卡关的情况,猫娘也很可爱很有陪伴感[strike](虽然一直在挂电话迫害她) [/strike],故事也非常有趣的算得上一个小品佳作,打折后性价比也非常高,推荐一般玩家入手游玩。[spoiler]女主竟然可以成为主角的妈妈? [/spoiler]
相当有意思的游戏设计和剧情,希望能有后日谈。
我玩的是英文版本,后来看中文版,感觉非常不一样!即使是相同的内容,用不同的语言表达给人的感觉也不同,因为背后的文化背景不同。非常建议用不同语言体验,来感受这种文化预设的影响。 [hr][/hr] 就游戏背景而言,它很好地展现了具有日本特色的网络与科幻文化。在游戏中,得以了解许多人的大致生活和在意的事,形成一种单方面的了解的关系,[strike] 并享受开盒他们的乐趣 [/strike]。 就游戏玩法而言,以阅读--推理的形式进行,有时我感到自己在做阅读理解题目,然而其中的悬疑给了这种探索足够的乐趣。这并非是一个硬核推理作品,其爽点在于享受推理一个只要条件合适,在现实中也可行且有用的课题。而游戏正提供了这样的合适条件为题干。 这是一部带有科幻与现实元素的虚构文学作品。[spoiler] 虽然我认为结局并不符合量子力学的科学规律,因为观测者理应无法决定随机观测结果(量子态的坍缩方向),然而这样的唯心主义世界观设定补充却带来振奋人心的温暖结局。 [/spoiler] 它是一种现实的类似与超越:如果这样的推理在现实中发生,作为双方又会如何感想呢?我们又应该如何健康地使用网络,在网络社区中成为怎样的人呢?

あ、これは凄すぎるわ よく作れたね
与红树林、鲁特里类似,但是太简单了。
总体还是好玩好看的,但缺点也真的很明显。 1.想法寓意真的很不错,但是结局揭示的时候又没有能把一切都串联起来的关键线索,只是一味陈述输出想法,整段垮掉。 2.玩法设计也太单薄了,真就只有时间线和资料库两个页面,看桌面还有几个应用结果真的就只是装饰。 3.作为一个要求玩家持续阅读文字思考的游戏,BGM让人听一会就想静音了完全不及格。
值得一玩
整体是个完整的还不错的故事,但是推理性未免弱了点,所有“案子”比起说串联起来更像是用胶水强行粘起来的感觉,导致分章节拆开来很多案却感觉每个都没怎么讲。被人推荐来玩是说推理性很好的新游戏,但是这个角度上难免令人有些失望。 UI很微妙,筛选功能其实还是很好用的,但是来回切的地方有点怪异,而且有些地方的操作有点迟滞(比如放特效每次都会卡) 本来以为是异能推理,玩了一阵发现是开盒推理,到后面发现其实就是开斯特盒盒,实际上相似的游戏反而是《全网公敌》那种,不过在操作性上比《全网公敌》还是要舒服不少的 令人不太满意的是收尾推理了半天告诉我真相其实并不关键,然后就包饺子了;虽然某种意义上是呼应主题,但是难免有些令人感到敷衍。 总之拿来当看故事的游戏的话还是可以的,奔着推理要素来玩就不太有必要了,质量本身还是过关的
喵斯特利亚可爱捏
有美少女陪伴的开盒模拟器() 推理难度不高,游玩氛围很轻松,前期的铺垫在最后得到收束反转的感觉还是很过瘾的,很完整的一个故事。 ed超级治愈,今天网络世界的大家也是很友善呢,真好。
