Prices
The United States storefront in every case, so this compares stores and not countries.
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): 56.83/day in the week to Jul 17 → 3.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,420 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.

生存难度比密教要低一些,但是没有控制台这一点又让难度比有了控制台的密教模拟器要高一些,不过你没有太多死亡机制的这一点又很好地弥补了你没有控制台的这一缺陷
43 hours in, still no idea what's going on. Also can't stop playing it. 10/10.
This is what I could only imagine being kidnapped by a game feels like

感觉很像合成大西瓜但是又整不明白的那种感觉,很迷,应该比较挑玩家……
Overall, quite an enjoyable title. It's a lot easier and more approachable compared to cultist simulator (perhaps it could be a bit harder, I guess), but it still requires you to do a lot of reading and figuring things out, so the first hours can be a struggle for a new player. + Lovely Lovecraftian setting + Nice writing and worldbuilding + Cool art style + Very laid-back with no rush to do anything, if you missed one opportunity, you can always wait for the next + Not as obscure as cultist simulator
I love Cultist Simulator, and other Fallen London games, however this has been a frustratingly obtuse experience. Insanely complicated UI with unintuitive gameplay. I love difficult games yet the in game mechanics are overwhelmingly underexplained. Having to alt tab and look up how to progress through the first hour of gameplay for the simplest mechanics doesn't bode well. The tiny prompts of information and flavor text disappearing before I can finish reading them was the final straw. No thank you. I so very much wanted to love this, maybe I'll try again one day.
i don't understand.
Awful game experience
一开始玩得一脸懵,不知道哪个卡要往哪里放,也不知道哪个槽能放哪些东西,好不容易打开了一个炼金瓶桥,打开了一个房间,却不知道第一个房间是可以放大的!!!放大以后里面的东西是能拿的!!!愣是以为只有村庄里的地方能玩哈哈哈哈,结果在村庄里玩了好久好久甚至迎来了第一个闰时。。 后来知道了怎么玩以后太上头了,但是九术登顶好难啊啊啊,而且小小一个游戏怎么操作那么复杂,多线程处理复杂事件仿佛在上班,每次玩完感觉自己仿佛过了一周的996生活一样疲惫(痛苦脸
Much like the rest of Weather Factories body of work, you will need to enjoy reading. For this game in particular, you will REALLY need to enjoy it. Being the librarian of an abandoned esoteric estate requires a lot of reading; and close, focused reading at that. Note taking is recommended(and if you want to avoid the wiki, really required). The lore, writing and visuals all create a stunning experience that any fan of cosmic horror will easily enjoy. Progression can be a bit opaque at the beginning, but reading everything carefully (and good notes) will smooth things out considerably.
