Several diaries gradually reveal the thrilling story of a missing case; after multiple deductions, are the answers in the past or present? With frequent plot twists, you never know which is the truth and which is the unexpected; in a dense fog, time buries the past, but the marks remain.

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.

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

The Diary is a 2D suspenseful narrative puzzle game that revolves around several distinct "diaries," including a journal full of life but full of doubts, two investigative notebooks written by different people, and the planner's diary, which will all be displayed before you.
By solving each page's puzzle, you will turn the pages and gradually gain insight into a heart-stopping missing case. From different perspectives, you will uncover the buried past behind the case.

· Open an unknown diary and search for its owner while solving puzzles
· Among 6 characters, whose perspective are you reading the diary from?
· With multiple reversals, the answer may be right in front of you or it may never appear

Reviews
表现手法确实挺有意思,但是这个剧情实在是很没意思。
解谜很简单,画风非常唯美,是值得一玩的游戏。
