Modeled estimate, not a reported figure. How we estimate →
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.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
No United States chart position — it charts only in the markets below.
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): 54.14/day in the week to Sep 1 → 98.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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.
About
A mischievous fairy has left the once-majestic library in utter chaos. The principal’s word is law: "You are forbidden from leaving until all 3,072 books are returned to their rightful places!" In the silent, mystical archive, your long battle against the mountain of books begins.
Categorization: From Destructive Magic and The Travels of Otherworld to Romance Novels—use titles and cover designs as clues to transport a massive collection to the correct sections.
Massive Volume: With 3,072 books to organize, the task may seem overwhelming at first. However, as you stack each book, you will unlock magical abilities that drastically boost your efficiency.
Visual Satisfaction: There is a special joy in seeing the books that once cluttered the floor return to the shelves, slowly revealing the hidden floor beneath. As chaos transforms into perfect order, you’ll experience an unparalleled sense of satisfaction.
Strategic Efficiency: How will you combine your unlocked abilities? What order will you tackle the mess? The strategic fun lies in your decision-making, as your tactics can lead to a dramatic increase in workflow.
Immersive Atmosphere: The library’s ambient sound and BGM change dynamically; as shelves fill up, the acoustic resonance grows stronger, drawing you deeper into the world.
The Principal’s Strict Evaluation: Your precision is being monitored. The Principal’s evaluation shifts in real-time based on how many rows are "correctly shelved" according to the rules. Accuracy and speed are the keys to a perfect score—and your escape.
Assemble: A spell that summons other volumes of the same series directly to your hands.
Insight: Highlights other volumes of the same series, making them easy to spot even in a disorganized pile.
Auto-Shelving: A spell that instantly places the books in your hands onto the shelves in perfect order.

certainly a game with merits that loses all of that when you understand that ai was used during the creative process. ai has no place in game-making, and it strips away any heart which could have been present within. i would have loved for there to be a modicum of depth to the world we see, perhaps a small blurb or passage which unlocks upon completion of a shelf. unfortunately, this is not a game with depth, nor thought, nor creativity.
Игра медитативная, не нужно куда-то спешить, можно под разговорчики играть. Советую пройти первый раз игру без спеллов, не нужно ставить себе цель как можно быстрее все книжки по полкам расставить, вы от этого просто ничего не получите и заруините экспириенс, потом со спеллами выполните.

一玩就上瘾了 好喜欢图书整理的工作 本人是喜欢边整理边翻阅的那种类型 要是可以给每本书加一点文本就好了! 然后每套书的文本都是连贯的 每凑齐一套书便相当于解锁了一个完整的阅读体验 这样子我真可以在这个图书馆呆一整天 而且有时候看了书的内容才能更好判断书的分类! 最后我真的很需要那本避免被说“heal diff”的书!!
I've played the game for a good 3-4 days and all have been well. I've gotten up to 1,400 books so almost half way and accumulated a total of 14 hours of gametime by then. Then one afternoon, I decided to play it again but the game would not load my progress. I felt as if the 14 hours I spent grinding the game had gone to waste. I do wish an explanation or anything
15시간정도면 모든 도전과제를 깰수있네요. 마법쓰고 2시간20분만에 클리어하고 나머지시간은 마법없이 정리했어요. 정리하는거 재밌었어요.
As a few other reviewers have noted, the AI disclosure for this game was added later, leading people who otherwise would not have supported this game to purchase it. 1) That's trashy as hell. 2) There is no reason you needed to use AI at all in this game. I'm not gonna be like some others and assume you were lying about the extent, so assuming you were honest, you could have easily done those things without relying on generative AI. The concept was good, the gameplay was good, some of the book titles were extremely funny, and yet you decided 'just a little' genAI was fine? That's like baking brownies and thinking adding 'just a little' dog poo was fine. Do better.

autism activated. 20/10. i need MORE
Fellow neurodivergents, we meet again
I was finally able to do the last achievement after an 18-hour run, counting the times I went AFK. This was absolutely insane to do, yet it was so satisfying to see the blue lights on every category after using no magic at all. It had been a while since I played a game that made me stay up so late day after day without me even noticing.
