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 2,515 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.

It's great, I love it. In terms of overall enjoyability, I think I prefer CS since I still need to get an ending with BoK. Problem is, when you leave for a long time and return on your 1 month old save, you just feel overwhelmed and a) leave the game b) you just wanna restart from the beginning. Otherwise nothing else to say. Amazing lore. Peak writing (altough sometimes complicated when english is not your native language)
游戏还是比较有意思的,虽然剧情比较散碎,但是能从各个文本上窥见作者构建的神秘学世界观的庞大。如果不看wiki或者别人做的总结可能会有点云里雾里的。这个游戏的世界观承接密教模拟器,游戏的基本逻辑也是一脉相承的,如果玩过前作的话适应起来会比较快,这一作其实也就只是多加了几个性相而已,本质上还是神秘学合成大西瓜。 缺点之一是这一作的指引不是很明确,不过我还算是比较喜欢在这种位置的框架下去摸索的,每次发现新的配方或者奇妙的组合都会很开心。 另一个缺点是游戏的推进过程太过于繁琐了,作者为了控制你的游戏推进速度设立了种种门槛,升级技能需要同性相的回忆,随着等级增加而依次增加,而同一回忆不能存在多个,所以越到后期需要的回忆越多,低级回忆就那么几个而且还不能留到第二天,所以就需要先废很大的劲做一堆可保存回忆,然后凑齐了才可以升一级技能。而解锁房间则需要使用带有性相的物品,这个也要废很大的劲去做,到后期为了解锁一个房间可能就需要花一天的时间做好道具,因为解锁房间用的道具基本是一次性的,所以每次解锁都要重新做。我也搞不懂为什么不弄点永久性的装备,设置的难一点也能让人有点成就感,也不会让游戏的时间曲线变得这么离谱。 以上种种解锁的限制给人的感觉就是操作时间指数增长,比如第一级只要花10s游戏时间,那么第二级就要20s,第三级40s,以此类推,而这个游戏有9级,我目前玩了40小时感觉差不多已经体验完所有的内容了,唯一的可能就是还有一个最终结局会有特殊操作,别的在我看来,从六级到九级是没有什么区别的。看别人的游戏时间推算也是,玩到结局大概需要九十小时,后面几乎全都是在重复劳动合成大西瓜。

好游戏
好玩,喜欢玩。从同世界观第一部来的,司辰之书没有那种紧迫感,虽然依然是大量需要查Wiki的内容,但是不那么着急了,一个方案没了还有下一个,错过了一个还有下一个,总有解决方案的。不过刺激感较少,适合我这种讨厌对抗性游戏的玩家。
I found Cultist Simulator to be neat, and was really hoping this would be an evolution on that formula. And it kind of is. The base mechanics are still there and used in nifty new ways. There's just a few things I cannot get over no matter how hard I try. First, the UI is a ♥♥♥♥♥♥♥ unredeemable mess. Once you get rolling and have a good amount of skills, soul elements, etc, the buckets at the bottom of the screen just get insane. And god help you if you want to find a skill with a specific Aspect. Yeah, you can click the aspect and it will momentarily highlight everything that has it. But that means you need the bin of skills pulled up, which takes up half the screen. It's just annoying and makes playing the game a chore. Additionally, you frequently need to find a combination of things. For example, I need a workbench that can evolve Hushery and allows Winter to be slotted. There is no way to search or highlight that combination. You can highlight one attribute at a time. So, you spam click on a workbench to highlight all of them, then you spam click Winter, and try to look for where they overlap. And this is in an environment with a ♥♥♥♥♥♥♥♥ of clutter. The game desperately needs a search function so I can find the specific combination of things I need in the moment. Forcing me to manually look for it in the mess of the house adds nothing to gameplay, it just makes it annoying. The last thing which really put the nail in the coffin for me, there are several puzzles where you need a specific thing, but the thing is determined by RNG for no reason. The best example is Assistants. You need assistants to help open new rooms. You also need them to be at or above a certain level in a certain aspect. Each assistant comes with a base of 4 in 3 different aspects. You can buff them with a memory, a soul aspect, a food, and a drink. Food and Drink are a ♥♥♥♥♥♥♥ nightmare to sort through and generally don't give enough of a buff to make a ton of difference. So mostly, it is memories and base stats. Of memories, weather is the only way to get large buffs. A memory from a book gives you +2 sky, the weather outside being stormy gives 4. You can't control the weather, but you can be patient. So let's say you have a high level Sky room you want to open. You level up your Phost as high as you can to get a boost to sky. Then you wait for it to storm, so far so good. How do you get an assistant with a base of 4 in Sky? You roll the dice at the inn. It's completely random. Oh and you can't keep the assistant over night, so you have a limited number of rolls for the day, before the weather is gone and you lose your chance. Even more infuriating, you need time to buff the assistant, so later in the game you have to roll the right one on the first try. Get anything else and you miss your shot. It is purely frustrating. It isn't making the puzzle more interesting or harder. I have solved the puzzle, I know the combination of things I need to do, don't make me pull the lever on the slot machine 100 times to input the solution.
I want so, so badly to be the kind of person who loves this game. But god, it's so frustrating, overwhelming and tedious at times. The lack of tutorial or any sort of guidance has you floundering in the dark, unsure of everything you're doing. It's not at all intuitive, and it can really make you feel stupid when you do try to look up tutorials or guides and everyone else seems to take to the game like ducks to water. It's honestly such a shame because it is such a rich world, and the concept of it is so appealing, but the clunky UI and inhospitable nature of the mechanics makes it super hard to adapt to. Will I continue to try and master it out of pure spite and frustration? Yes, but I would not recommend this game to just anyone. Like many reviewers say, it really doe stake a specific kind of person, and I so wish that person was me.
Really good
玩起来非常上头,超级杀时间。 只通关了一次。 不知不觉中内化了那些象征和符号在意识和文化中的存在,很回味。
有点太好玩了
