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.

推理ものがしたーいと何気なく購入。 面白すぎてクリアまでずっとやってしまいました！ 見慣れたタイムラインから情報を整理して真相に近づいていくのはすごく楽しかったです！
オカルト・哲学・量子力学みたいに、この世界を疑う事が好きな人にはぶっ刺さります。 謎解き自体はこの手のゲームを好んでる人からしたら普通or易しめくらいの難易度で、苦手な方にはヒントもあるので攻略に詰まることはないと思います！ 大筋のストーリーが本当に良かった！
なるほど、よく出来た未確定でした。 堪能。
ツイ廃にはたまらんゲームシステム、解像度高杉
It becomes a bit easy to brute force the game once you know how it works, an additional layer or two of complexity as a "hard mode" would have been nice. I enjoyed everything overall though. Good non eroge VNs are hard to come across and I'm glad I played this one.
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。
A delightful little mystery/deduction game with great flavor and an ending that really brings it all together in a fascinating, satisfying way. If you're someone who enjoys the mystery + pseudo-physics vibes of something like the Zero Escape series, Steins;Gate, Somnium Files, etc. and you're down for some light deduction gameplay, I think you'll really enjoy this.
ツイッターに似たSNSの情報を下に状況を予測していくミステリーゲームです。 難易度も程よくコンプリートまで夢中でプレイできました。 ただのタイムラインを眺めているだけなのに、 登場人物それぞれの背景や人となりが見えてくる流れが非常に秀逸で面白かったです。 現代のネット社会あるあるをこれでもかと詰め込んでおり、 「あーこういうの居るよね」ってずっと思いながらプレイしていました。 現代推理ものが好きなら内容もコンパクトですしプレイして外れはないと思います。
面白かった。 「都市伝説解体センター」のSNSパートと、「未解決事件は終わらせないといけないから」を足して2で割ったような、といえばわかる人にはわかるか？ 自分は読んでもよくわからなくて、「この書き方は女」「この年齢なら階級付き」「この発言はコレとイコールだから同じ人」みたいな解き方してましたが、普通にクリアできました。 ヒントがありますが、画面右のヒントが多くあえて使う必要は無かったです。 SNSの悪意を見ながら当てはめていくのが面白く、オチも結構良かったです。
面白かったです。ゲームを始めて最初は「あれ、これは何かの続編なのかな？」と誤解しましたが、これ単体できちんと作品でした。推理難易度はそんなに難しくなく（一応7時間でヒントなしで全エンド行きました） 全体的な雰囲気も良く、いい作品だなと思いました。 トロコンできてないので、もうちょっと頑張ってみようかな、と思わせてくれる作品です。
