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.
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.

Very nice game
Most of this game was replaying the first game, even at 50% at $2.50 it is too much. I even liked the first one as not polished as it was but the 2nd was just pissed me off. Also abandoned game, 2017 was when the third chapter supposed to come out and that never happened.
we need chinese, we need chinese, we need chinese. 我们需要中文。救济性好评,不推荐。202211上,t a o宝,本平台,本平台充值折扣掉卡,indie gala,fanatical,humble,它处自定义包入的本体约2元。兄弟萌,强烈建议不要第三方平台的小店买y u额,通过饰品等挂steam市场转的,高概率red信乃至封号,且行且珍惜。爱人如己,目前就这,看以后追评。

Прошел первую част и теперь пишу о второй плюсы и минусы +Как и в прошлой части это графика, локализация, геймплей и хороший фон профиля стим +Улучшена оптимизация и теперь можно поиграть без лагов даже на средних настройках +Логичность игры очень порадовала, нет каких то моментов которые не раскрывались бы в игре теперь минусы -Очень многое взято из первой части -Так же как и первая часть игра проходится за чуть меньше часа На этом все жду продолжения А покупать или нет решайте сами
Это квест, где ошибка действительно человеческая, особенно твоя. Игра постоянно намекает, что ты что-то упускаешь, и она права. Загадки выглядят умно, пока не выясняется, что решение лежало у тебя в инвентаре уже полчаса. Сюжет загадочный, атмосфера напряжённая, а главный источник ужаса — осознание собственной невнимательности. Итог: красиво, странно и немного больно для эго. Пройдено!
Στα [+] • Μπορείς νά τό παίξεις μέ τήν ησυχία σου γιά νά σού φύγει η περιέργεια (άν έχεις) καί μετά νά περάσεις από τό ταμείο καί νά ζητήσεις πίσω τά λεφτά σου! Η διάρκειά του δέν θάχει ξεπεράσει τίς δυό ώρες... Στα [-] • Συνολική διάρκεια παιχνιδιού: γύρω στά 90 λεπτά. Αν τώρα αφαιρέσεις τά 40-50 λεπτά πού αποτελούν επαναλήψεις από τό προηγούμενο Κεφάλαιο κι άλλα 10-20 πού καταναλώνονται σέ διαλόγους καί ανούσιο ποδαρόδρομο, μένουν γύρω στά 20 λεπτά κανονικού παιχνιδιού!!! Ισα-ίσα δηλαδή γιά νά βρείς άλλο ένα πτώμα, νά κάνεις τήν προφανή διαπίστωση ότι πυροβολήθηκε από τό παράθυρο τής εκκλησίας (καί τί έγινε δηλαδή πού τό κατάλαβες;) καί νά έχεις τόν χρόνο ν' απαντήσεις στό ύψιστο υπαρξιακό ερώτημα: ποιόν θέλεις νά σώσεις, τήν γυναίκα σου ή τόν κόσμο; http://adventures-index10.blogspot.com/2016/03/the-butterfly-sign.html
