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 Jul 30 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.
About

In Silent Walls: Subject 13 is a first-person psychological horror narrative game.
Twenty years after the disappearance of your sister Elina, you return to the abandoned Red Hollow Sanatorium to face the past and uncover the truth hidden within its silent walls.
Explore decayed corridors, discover disturbing documents and drawings, and slowly piece together the story . Every step brings you closer to the truth… and to madness.
Because within these walls, the past is not just a memory… it is waiting for you.
Features:
An immersive and realistic atmosphere powered by Unreal Engine 5.
A dark, story-rich narrative, revealed through letters, documents, and the environment.
Exploration and light puzzles to progress through the story.
Terrifying and unsettling scenes, focused on psychological horror rather than gore.

The raw jumpscare and exploration style takes me back to good old indie horror game days of 2014. Good job on your first project!
BOLEY LAAA .
30分程でクリア出来る短くまとまっていて分かりやすい短編ホラゲ ジャンプスケアが単調なのがちょっと残念 導線も分かりやすく迷わないので軽めのホラゲがやりたい人におすすめ

Short exploration game. Has some good jump scares.
Engaging story, creepy atmosphere, and the jumpscares will get ya. Only complaint...very short.
Jeu très sympa à faire, j'ai bien été surprise par les screamers, je crois que mes cris se sont entendus depuis la rue. Merci pour ce joli travail et cette belle réalisation ;) Le jeu est bien ficelé, tout est ludique et bien pensé, l'histoire est sympa et donne ce qu'il faut d'émotions.
BGMや雰囲気も良く適度なジャンプスケアで楽しめてプレイ時間も1時間程なのでサクッと遊べてストーリーも短編物としては良かったです。 マウス感度とか調整出来たらなとは思いましたがその点を差し引いても中々に良かったです。
Very good game. It creates a spooky environment and I loved the strange story. Has some good jumpscares. I wish the nighmare would have been longer.
ホラーゲーム初心者向けの心理的ホラー作品。 ✅ 良い点 ・分かりやすいストーリー展開 ・30分程度でクリアできる手軽さ ⚠️ 気になる点 ・ジャンプスケアがワンパターン ・最初の扉にある暗証番号を3回間違えると警報が鳴り続けてストレス ホラーゲーム初心者には最適だが、ガチ勢には物足りないかも。 価格を考えれば妥当なボリュームと内容。
とにかく怖かった…! じわじわと真相に迫っていくストーリーが本当に面白くて、先が気になってどんどん進めてしまいました。 グラフィックも綺麗で、世界観に引き込まれました。 最初に怪異が襲ってきたときは、思わず悲鳴を上げるほど😂 緊張感たっぷりの探索ホラーが好きな人におすすめです!
