Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
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): 0.29/day in the week to Aug 31 → 0.86/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.

游戏底子不错的,但是bug好多 ============================ 神人游戏,主线和一个支线都要复原汤药,要洋葱这东西,我翻遍所有地图没见过
I dont get too psyched about craft games that are overly serious. This one feels casual and a better fit for me. The monster girls are the obvious carrot, I like them. The game can feel a little off if youre using controller but I just used my mouse for some actions. Had to use a mouse for the floor 7 boss.
挺好玩的 就是BUG太多了 不过好歹不影响游戏进程。

я не решила, что в итоге хуже баги в этой игре или отвратительный перевод
esta bueno el juego pero tiene un problema cuando conectas un control, no puedes asignar bien los botones del control
2026/06/22 v1.0.9 全成就 簡單的物流工廠,不用太認真蓋 打怪爽感算夠,吸血太強 種田偏麻煩,交給魔物娘就不用管了 劇情可以倍速,好評 部分UIUX設計不直觀 無法預覽裝備升階結果、道具很多但沒有分類且不能搜尋、食譜超亂 看的到前面版本的痕跡 如: 商人說明不同商人賣不同東西,但事實上野外所有商人都賣一樣的物品 也看得到預留未來版本的欄位,不知道還會不會有 後期升階資源有點脫台錢,剛好解一些浪費時間的成就
Das Spiel ist m.E. ganz gut. Es ist nur irgendwie schade, dass es keinen COOP-Modus gibt.

해본 자동화라 적힌 겜 중에 제일 불편한 게임
Also für den Preis von 9,89€ (im Angebot) "war" das game zunächst ganz ok. Bis zu der stelle wo ich immer wieder einen Game Breaking Bug hab. :/ Nach 12,6 Stunden bin ich am Boss Kampf mit Zoe angekommen, und der ist einfach nicht machbar. Sobald sie diesen... ich sag mal 1000 Fäuste Angriff ausführt. Fliege ich durch alle wände, quer über die gesamte Map, und kann nichts mehr machen. Am liebsten würde ich es zurück geben, aber da ich deutlich über der Zeit bin lässt sich da wohl nichts machen.
