✦ AI summary

Idle Library is a straightforward incremental game with a relaxing progression loop involving collecting books, hiring librarians, and unlocking research upgrades, but players consistently criticize its lack of depth, poor UI design, missing tutorial, and minimal content that feels exhausted within minutes. Common complaints include generic visuals obscured by white overlays, tedious repetition even by idle game standards, poor quality control suggesting heavy reliance on AI-generated assets, and lack of engaging features to sustain long-term play.

You get 5 different AI backgrounds to choose from, some piano music and when you click, some numbers change. There is NOTHING ELSE. You are looking at the background through a heavy white/fog filter and watching numbers go up very slowly, getting an achievement sometimes. I've played other idle clickers and they would at least give you SOMETHING - funny descriptions, a little animation, new small pictures with a new level, change of a sound effect, something spawning on screen, whatever - just SOMETHING else than just some numbers and the same background and same soundfile playing. "Dark mode" also just means dimming the screen, so it's even more dull than with the foggy filter alone and harder to read. I mean - it's free, so nevermind. Still a time waste though, that's why I've stopped playing already.

All progress wiped out :(, 22 hours down the drain. simple game, you have backgrounds but the white screen blots it out so it looks very generic.

Props for developer to make a game, it takes effort. But with 15 min playtime and 14 acivements. I already feel like I know the game and are done. The main word I have for this game is AI. The description says "All AI-generated content was reviewed and edited prior to inclusion." And this makes me question how mutch time was used to make the game compared to review AI-generated content. This game i flat, UI and symbols are badly sized. Missing any QoL, I had to jump between pages to see my currency and what I can purcahe with it. Dark mode is a brightness reduction. No tutorial or any helpful information, just had to click around until I found the clicker button, and any or all functions. Game was released 16.03, last update 21.03. And the dev is promoting a new game. Says it all.

Idle Library is a simple incremental game where I start with a tiny reading room and slowly turn it into a much bigger library. The basic loop is exactly what I expect from an idle game. I collect books, improve my production, hire librarians and keep upgrading things so the numbers grow faster. It is a very relaxed experience, and I like that I can either actively work on upgrades or leave it running and come back later to see how much progress I have made. The progression is where most of the game gets its value for me. I can improve the way books are collected, unlock research upgrades and build towards bigger multipliers as my library develops. The research system gives me permanent improvements to work towards, while special collections add another reason to keep increasing my production. It is not a complicated strategy game, but there are enough upgrades that I can spend some time deciding which improvements are going to help me progress faster. The prestige system also gives the game a much longer loop than the first few upgrades suggest. I can renovate the library, reset my current progress and receive permanent bonuses that make the next run faster. There are also daily…

No tutorial just aimlessly clicked til something worked. It's ok if you need something to help you fall asleep.

Shallow idle, not idle game that will test your Google-fu in order to find a decent auto clicker. It needs more such as a story or some reason to keep it open.

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
