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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.

Got this before i realized it was AI. Not gonna lie this game is too simple to be using AI. The idea is newish, but there’s plenty of menial task games already such as; digging holes, picking up leaves, sorting, cleaning, decorating whatever yk. So like they could have hired other artists for the book covers, the painting but I’m pretty sure it was all to test if AI games would sell. Cause now my feed full with AI trash games same font diff name. Sorry so long:( strong opinions
I regret playing this as much as I have, but only for reasons that exist outside the core gameplay. If you don't care about AI or it's consequences, play this. It's great. On with the rest of the review. There almost a dozen copycats of this game that have been created in under a year, and while this isn't the most complicated game to reproduce, all the copycats are from small or even single-game developers. That there is even a possibility that the devs of this one aren't as honest with their use of AI as they claim makes me worried that this is one of a long line of pop-up games from a single team, inventing new studios to cover their tracks as they release essentially the same game under multiple titles. The other titles all share a similar art style, and seeminigly run on the same engine. Something smells fishy and I don't like it. This was the one game I purchased that had the 'with AI elements' tag attributed to it, and because of this I'm getting recommended other games that have far less scruples with abusing AI assets than these devs claim. I regret even entertaining the thought that even a little bit of AI is okay. My advice to the devs is this: If you don't want to be lumped in with the egregious AI slop, don't use it at ALL. Claiming 'it's only here and there, and we all finished it by hand', is nice, but it still gets you lumped in with the lazy, scamming, no-love-for-the-industry publishers that are pushing for AI use. A drop of sewage in a barrel of wine means you now have a barrel of sewage. Learn and do better.

Looked forward to play it. but delayed addition of warning about AI generated content caught me off guard. There was no reason for AI to be used, and it soured my experience to the point I am not planning to complete it.
I sadly was past the return window by the time I had realized this game used generative AI in it's development. I want to be clear that this is not okay and I do not support it's use in game development. While the onus is on me to self police these things more carefully going forward, I cannot recommend this game in good conscience.
It was fun, and it was crafted well WITHOUT AI, but then you just, really, had to cram AI into it and practically hide it before being discovered. This dissapoints me so much.
I was disappointed to find out that I had unknowingly supported AI after playing the game. Tbh before I even found that out though the game was just ok. I definitely don't recommend especially because the things they used with AI could've easily been done with people.
Şuursuzca bir zevk alıyorum.
They use AI... Wish I had seen this sooner... Only got it because Smii7y played it.
If you actually do things with the powers they intend for you to use, then they game ends up being weirdly fast passed, and it completely removes the point of organizing when the powers do EVERYTHING for you. Also found out it uses AI, guess I should've read it better tho, still disappointed in its use none the less. Could've been nice if they put a little more thought into the design but sadly falls flat.
Heavy use of AI throughout it, not recommended.
