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): 1.43/day in the week to Sep 8 → 4.14/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 2,404 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.

話の展開は面白い。結構簡単だと思ったけど意外と難しいぞw。とりあえず値段もお得だから買いだな!
我沒看過一款遊戲END的人比BAD END的人數還多的遊戲,遊戲這價格跟劇情算不錯了。詳細有興趣再寫。
很好玩 所以快把新作端上来吧

很强很封神的一部作品
buena historia
8.5/10 叙事节奏上极其极其优秀。本作在推理方面并没有特别多的反转,出色的角色塑造和叙事能力足够吸引人
интересный сюжет, не очень трудные загадки
if you're slightly interested, avoid spoilers like the plague its like a classic Sherlock Holmes novel written by a japanese light novelist and if that interests you, you should check it out
留下了一堆坑。
强烈建议每一个选项前都进行存档!!!! 故事是好故事,就是整个流程略短,涉及到的解谜元素也不算太难,整个故事的走向也大概能猜到。 有一些突脸会吓一跳,高潮也此起彼伏,没有太多废话文学,总之比较推荐,属于开篇就引人兴趣的那种! 缺点是无法跳过搜索环节。
