Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
14 of 15 markets; the rest we haven't asked for this title, not markets where it is unavailable.
Availability
We put this game to every storefront we collect. A market that answered not sold has told us something about the game; a market we never asked has not, and the two are never drawn the same.
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/day in the week to Aug 13 → 0.14/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 2,402 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.

아트퀄이 들쭉날쭉하다는 거 빼면 전체적으로 잘 만든 인디게임. 소재부터 강렬하다보니 몰입감이 상당히 높아서 재밌음. 개인적인 희망으로는 도전과제 올컬렉을 조금 더 쉽게 할 수 있었으면 좋겠다. 콜렉션 딱 하나 남았는데 진짜 죽어라 안 뜨잖아.......

14 on sale1 answered “not sold”0 we did not ask
The 1 “not sold” market is read from the Steam price pass of Aug 23: that day the store answered for this game elsewhere and gave no price there. The 14 priced markets are the same rows as the table above — each the latest price we hold, dated here when it is older than that pass. The 0 marked “not asked” were not put to this store at all — either it has no storefront there or we do not collect it yet, and neither is a statement about the game. A refusal is a refusal on one day; a store can list a title again tomorrow.
