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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 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.

Unironically not bad at all.
護衛が対象から断りもせず離れてそれで死んで その理由が特にない・・・? どれが謎なのかどれが雑なノイズなのか解らない 何故お得意に頼まれただけで命懸けで島に行く? etc,etc・・・ 必然性と意外性がどこにもない、絵がアレなんだから他がその分良くて 評価されてるかと思ったんだけど全くそんなことは無かった。 兎に角「稚拙」でした。
게임 클리어 후 나오는 엑스트라 스토리에서 등장인물들 수영복 모습 나오는데, 감탄사가 절로 나왔음 개발자 취향 미친변태새끼인 게 분명함 스토리, 추리 별로였는데 그 수영복 씬 보고나니 추천 누를만한 가치 느꼈음

700円とか払ってミステリー文庫を買うくらいならこのゲームを買ってプレイした方が良い。
・本当に500円でいいんですか? ・作者は異常ガリガリ愛者のサディスト。 ・言うほどミステリじゃなかったけど、終盤はとてもアツくて良かった(小並感)。 ・声優陣が豪華すぎる[spoiler] ので、配役でなんとなく黒幕が予想できてしまった[/spoiler]。 ・EXTRAは作者の性癖展示場。
The story does an amazing job at keeping you hooked, and it was an overall really fun and enertaining read. The length might be a little short (taking me around only 9 hours to complete), but that's not a bad thing at all. Plus, it's only like five dollars WITHOUT a sale price! I was blown away by this game, and for it's small cost, I totally reccomend it. I would also like to give a shout out to the devs for giving us a Spanish translation?! I'm not even a native speaker, I just don't really see Spanish translations often for games like these. In terms of translation, both the English and Spanish version felt a little literally translated. Don't get me wrong though, the game is completely readable, and I eaisly understood everything that was going on. It's just something small I noticed.
推荐打折入。 看封面女主可爱才买的,叙事还算有逻辑,但玩儿下来发现最影响游戏体验的可能就是女主宁宁子的别扭性格。我对此无感体验就还好,一起玩儿的朋友很不喜欢宁宁子,打起来就有点痛苦了。 作为一款侦探视觉小说还是不错的,伏笔都回收了,重要部分的逻辑也都能讲通,喜欢这类风格推理的不要错过。硬要说缺点的话,(可能涉及剧透)[spoiler] 个人感觉从第五章后半段开始有点出戏。因为这是个日本游戏,剧情在紧要关头突然开始吐槽、莫名其妙燃起来、突然又开始煽情让我实在感觉不耐烦了。并且有时候能感觉到作者肯定有关注时事新闻,有时候又觉得作者的一些观点像活在二十年前……不影响游戏流程,只能说是个人体验上确实会有绷不住的时刻。 [/spoiler] 总之推荐打折入!
Esta bueno, jueguenlo
好玩,配音非常好啊,就是被耍了[spoiler]艾历克斯竟然不是正太[/spoiler]!!可恶!!
前期悬疑感做的挺好,但剧情合理性有挺多瑕疵的,经不起推敲,但总体对得起这个价格,可玩
