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.

Reviews
・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。
真没想到7块钱就能玩到这么有意思的游戏,剧情短小精悍,惊悚氛围感做的相当不错,宁宁子可爱捏。后日谈也挺有意思的,虽然有几个跳脸CG,但一般都能提前预判到,然后我就眯眯眼玩,嘿嘿,这样就一点都不吓人了。
这分扣给后日谈

前半部分悬疑重重,扣人心弦。后半部分略显平庸,但仍不失体验之乐趣。后日谈尤有别样之趣。
ワンコインなので期待せずにやったらかなり面白かった そしてEXTRAは笑いのレベルが別格だった
500円でフルボイスで作りこまれたシナリオ、ケロケロ、お得だわ
挺好的故事,配音是真的不错
后日谈还没打,前面都还不错
宁宁子可爱捏
