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 2,400 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.

Great mystery/horror VN with a surprisingly stacked cast (Ai Kayano, Yuka Iguchi, Kanako Ito???). I really enjoyed the murder mystery plot! It's a pretty simple whodunnit case, and utilizes the horror element quite well. There were some cheap jumpscares but it mostly relies on a dreary atmosphere to build suspense. I'm feeling a little mixed on everything past chapter 5 when it took a hard turn into paranormal/sci-fi, felt like the author just threw several ideas hoping it sticks. The ending is fine but the sci-fi stuff left a pretty bad taste... A very... doujin experience. a little rough around the edges but it has a certain charm to it. Excited for the sequel!

Return to Shironagasu Island is a special kind of visual novel. It might not have the best art or music and the first impression is a bit mixed, but it quickly turns all of that around with good writing and insanely twisted story. For the first 5 hours I had no idea what to even expect, because everything was so vague. "Is it a death game? Or is it a detective novel?". Turns out, it's neither. It starts off as a detective novel, continues as a death game and the latter half of the story is something else entirely. Despite all that, the story stays very simple to follow and that's what makes it very memorable. And yes, Neneko scores 10/10 on autism test.
色々詰め込まれたB級映画的な闇鍋ADV。とにかく広く浅く色んな物がぶち込まれている作品なので、純粋なミステリーADVを期待すると思ったのと違うと感じる。 値段が恐ろしく安く、手に取りやすい。ただUIやシナリオやキャラの掛け合いもひと昔の旧さなので良くも悪くも人を選ぶと思う。
有一些莫名其妙的小头剧情点和对话,例如偷窥女角色洗澡/撞见女角色洗澡。人物比例我就不说了,姑且算做是“独特的画风”。
很不错的一款本格推理,剧情风格有点类似阿加莎但没有雷同,难度不算太大,非常舒适的节奏。虽然立绘潦草,但配音太牛逼了,这里直接给到一个夯👍

单纯看恐怖悬疑还是非常可以的,画风人物比例有点崩,有些剧情真的多余了
メーカーロゴからオープニングの流れ、BGMとクジラの鳴き声的なSEがステキ!タイトルもエモい! キャッチコピーもイイ! 前評判がメチャメチャによかったのもあり、俺は今名作を始めたのだ…!というワクワク感と共にプレイし、期待通りに十分楽しめたのでおススメ。
