“I apparently have over 500 hours in this game and have never written a review for it, so it feels about time. The strength of this game lies in its writing, and in the way the mysteries of Hush House are so well…”
“Don't be fooled by the cards. This is not a card game, it's a crafting game, and the cards merely represent the ingredients and objects you use to craft things. As for what you're crafting in this game... effectively…”
“When I started playing Book of Hours, I was apprehensive about it. Cultist Simulator, Weather Factory's previous game, had fascinated but ultimately stressed me out. How grateful I was then, when I found out that Book…”

“I adore the art, the music, the concept of the game. I refunded after a short play, as I came to the conclusion that that the lack of in-game guidance at the beginning which left me at a loss with no groundwork of…”
“I really wanted to love this game. It has a lot of really awesome ideas, great art, music, theme, etc. The problem is the game mechanics are just too opaque. Even after 25 hours, the basics of crafting and upgrading…”
“I think this is the game I wanted to play compared to Cultist Simulator. It feels like the developers listened to what main hangups from that game and mixed it up to make something real special. Rich lore, beautiful art…”

“Fun game not for casuals.”
“One of the best puzzle games ever. With it's incredible depth and lack of fail-states, Book of Hours makes a perfect game for a short session or hours of time lost to the unmatched worldbuilding. 10/10”
“If you loved Cultist Simulator lore and world building, but wanted a calmer less hectic playstyle, this game is perfect for you.”

“This is an exercise in writing a Wiki. Or using the existing one and writing your cliff notes. The interface looks pretty but in a exercise in frustration. Moving the map around is on the same mouse button that picks up…”

“Incredible. Cozy and disturbing. Beware spreadsheet hell.”

“Level up system is really bad. Reminds me of Morrowind and Oblivion. To get the most out of it, you can't just level up what you want and enjoy the game. The game heavily encourages awkward gameplay, ignoring level up…”

“这游戏已经在凑凑乐上走远了，变成了一个纯凑数查攻略的解密游戏了，从文本上和前作差太多了，玩起来倒还行，就是凑得发昏，前作还是一个半解密的文字游戏，这一作文字功底差太多了，当个rpg玩倒还行，但是当文字游戏和密教模拟器没法比”

“[h3]Confusion is a question, and the gamer's answer is always Yes.[/h3] What if I told you this game left you washed up on a beach with no instructions, forced you to read hundreds of pages of text just to try to puzzle out what is going on, and made Monopoly look fast paced by…”
— a player, Steam review · 289 hrs played“Legitimately my favourite game of all time. If you like study, the feeling of learning things, the feeling of finding use for abstract and esoteric knowledge, this is the game for you. This is not a game about being a wizard - this is a game about the joy of becoming a wizard,…”
— a player, Steam review · 185 hrs played“Tedious, shallow, dreadfully repetitive and ultimately unsatisfying. Beneath Lottie Bevan's charming artwork and Alexis Kennedy's meandering cultic lore is an awkward inventory manager and an overly convoluted crafting system. You play not so much as a librarian as someone…”
