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 · Poland over the last 30 days: the 21 chart moves that followed a price cut of more than 20% went a median of 12 places towards #1, and the 2,501 moves with no price cut behind them went 1 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.

Reviews
Weird card flipping gameplay with some of the best prose ever written for a video game. Unlike Cultist Sim there are now visuals which adds a lot of life to the whole experience. Also unlike CS, there's a cozy atmosphere to it all with no real dangers, though it can get a bit frantic when you're gathering higher levels of aspects. Fantastic piece, I love it. Don't think I've ever felt this rewarded just from getting a few new paragraphs of text in a game.
Great vibe and engaging progression minded gameplay loop.

Just the absolute best game ever! I'm obsessed
I love making flutes out of nothing but insights and a little bit of wood, and using these flutes to make more insights that help me make more flutes! the gods of sky favor me lots, I wouldn't have it any other way.
A game that has stayed with me. I would not bother with it if you don't have a second or third screen to keep the wiki up but the lore between this and cultist simultor will haunt you for the rest of your days
Going off the reviews, I was not sure if I would like this game or not but I decided to try it out. To my surprise, I'm actually really enjoying it. I don't think I'm quite clever enough to puzzle my way through on my own but with four wiki tabs, a couple steam threads, and the occasional reddit post open on my phone, I seem to be plodding along quite nicely (The reviews were really not joking, there is a STEEP learning curve). I love the artwork and the card based gameplay is new and interesting for me, so I'm having a great time.
I like the game! It has a similiar feel to cultist simulation and failbetters game Sunless sky and sunless sea. I love to read and discover the mysteries of this game's world.
Хорошая игра. Дополнение стоящее
好玩爱玩多玩,适合喜欢密教的,玩法和难度上都比密教模拟器难一点,推荐多上wiki查一下各种数据,第一把可以了解一下操作,第二把再好好玩。
