Idle Library changes
Idle Library — Major Update: The Grand Overhaul
First and foremost, thank you for your incredible patience. I have been listening to your feedback and this update represents the most significant changes to Idle Library since launch. I hope it makes the game feel more rewarding, more strategic, and much more worth your time.
⚖️ Balance & Progression
Raised the first prestige threshold from 10,000 → 75,000 books, so reaching prestige feels like a genuine milestone
Steepened prestige scaling — later prestiges now require significantly more effort
Post-prestige upgrade costs now scale harder, making each prestige cycle feel distinct
Ascension now requires Prestige 15 (up from 10), giving the mid-game more breathing room
Moderate base cost increases across early upgrades to slow the opening hours and make each purchase feel meaningful
The Curator upgrade has been reworked — it no longer reduces research costs (those have been reset to fair values). Existing Curator purchases have been automatically converted into equivalent passive income, so no progress was lost
🏛️ New Upgrades
Two new mid-tier upgrades added to fill the dead zone between Curator and Grand Librarian, smoothing out the late-game progression curve
🔬 Research Overhaul
Two new research categories added: Philosophy and Mathematics
Research is now unlimited — purchase as many levels as you want
Synergy bonuses now only trigger when ALL five categories reach the same milestone together (5/5/5/5/5 = Tier 1, 10/10/10/10/10 = Tier 2, etc.), rewarding balanced investment over grinding a single category
📜 Quest Overhaul
Completely rewritten quest system with more quest types, more variety, and better rewards
Quest rewards now scale with your prestige and ascension progress, keeping them relevant at every stage of the game
Quests can now reward Boosters on harder objectives
⚡ Boosters Reworked
Boosters can now actually be earned — through quests, daily rewards, and the gem shop
Boosters now serve a real purpose in your daily play loop
⭐ Ascension Perk System (New)
Introducing Ascension Perks — a permanent progression system that survives prestige and ascension resets
Earn 1 Ascension Point each time you ascend and spend them on a deep perk tree
Branches include: general income boosts, tap specialization, passive income specialization, research bonuses, booster upgrades, quest rewards, gem fortune, prestige multiplier bonuses, ascension multiplier bonuses, and the ultimate Omniscient perk
Fully unlocking everything requires many ascensions, giving long-term players a meaningful goal
🏆 Achievements Expanded
Massively expanded achievement list — now includes achievements for far more than just book counts
New achievement categories: Prestige milestones, Ascension milestones, Research synergy tiers, Perks unlocked, Total clicks, Quests completed, Boosters activated, Daily rewards claimed, Gems earned, and Book Festivals hosted
📖 Narrative & Milestones
Three new milestone messages added to fill narrative gaps in the mid and late game
💎 UI Overhaul
Major visual and layout improvements throughout
Upgrade buttons now display your effective gain (accounting for all active multipliers) so you always know exactly what you're buying
All notification messages now show properly formatted, multiplier-adjusted values instead of raw base numbers
Numbers now format correctly all the way up to vigintillion
Offline earnings message now shows the actual amount earned in a readable format
Special Collections page now includes an explanation of how the system works
Research page now includes an explanation of how the system works
New Ascension Perks page added to the navigation
Thank you again for your patience and support. I'm an indie developer learning as I go, and your feedback means more than you know. I'm sorry for any rough edges along the way — every update I ship, I learn something new. See you in the library. 📚
