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): 0.14/day in the week to Aug 28 → 0/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.

Keine Einstellungsmöglichkeiten, schlechte Performance, man startet sofort im Spiel, Kein Anspruch und in ein paar Minuten erledigt. 50 Cent wären ok, aber auch kein Cent mehr.
とてもシンプルな異変探しゲームと思っていたら回廊は続き、 謎解きゲームに変わっていました。 色々な要素がありつつとってもコンパクトにまとめられていて良いと思いました。 ボリュームもクリアまでは30分かからない程度で、 異変も比較的わかりやすいと思いましたが、 全体的に薄暗くプレイ環境によっては異変を見逃しやすくなるかもしれません。
