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 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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.

Reviews
Book of Hours is an extremely complex, yet relatively calm, rich, and fun game with MANY riddles. As with most things by Weather Factory, the game has a ton of depth and not a ton of explanation. In fact I would even state that I believe this game is there most complicated. However, you are given time, in abundance actually. There are slower parts and it's easy to get stuck, but progress feels rewarding and you'll never be punished for doing something "wrong," at most you'll have a setback that is more than recoverable. If you stick with it and see it through I think many people would enjoy this Oh also, one last thing if you get REALLY REALLY stuck, just use the wiki. It's a single player game after all, not a standardized test, there's more depth to this game than any one person could reasonably discover on their own without a little help. Summary / tldr: 8/10 - Fun and calming - Can take at your own pace - Super Complex and in-depth, for better and for worse
no way to play. not sure what this is supposed to be. Nothing to click on. no keys on the keyboard do anything. WTF?

挺好玩的就是有点杀时间。
很不错,从密教入坑司辰
作为密教模拟器的续作,在保持了原有的设定上,做出了扩展,相比起前作,司辰之书的节奏更加轻松一些。难度也比前作更简单,玩起来就像在午后喝一杯醇香的红茶一样,恬静且美好。这就是图书管理员的生活啊
I beat the game once, learning to play mechanically. Now I'm starting a wiki to collect all the info I can and *understand* the game. (Yeah, wikis are already out there, but this is for me to learn the material.) Yeah, I'm studying for a game. That's how much I love it.
Love the vibes, and how chill it is lowkey dissapointing that some crafts are almost... unneeeded. But that's minor, for me
Amazing
