Library of Ruina

About Library of Ruina

Project Moon dropped Library of Ruina on August 10, 2021 as a standalone adventure and turn-based strategy title. You play as Roland, a low-grade Fixer pulled from the City into a mysterious building run by Angela. This place forces guests to fight for their lives against the Librarians guarding the halls. The core loop involves surviving these deadly encounters where losing means you become a book. Winning grants you access to new stories and upgrades your library's power. The game launched on PC, PlayStation 4, Xbox One, and Nintendo Switch. It mixes heavy narrative with tactical combat in a dark, surreal setting that feels distinct from standard RPGs.

Gameplay

Sessions revolve around turn-based battles where you command a team of characters to take down guests who appear like stage actors. You manage resources called Librarians and books they transform into after defeat. Each fight requires you to position units carefully and use abilities that deal damage based on luck or specific stats. Between battles, you explore floors, unlock new rooms, and recruit stronger fighters to join your roster. The interface tracks your collection of books which grant passive bonuses for future runs. Combat feels tense because every mistake can end your run instantly. You must balance risk with reward as you push deeper into the library to find that singular perfect book.

What Players Think

Players on PlayPile and critics alike rate this title highly with an IGDB score of 89.3 out of 100 based on 13 ratings. The community mood leans heavily toward intense appreciation for the storytelling and combat depth. Average playtime hovers around a marathon session length as players chase completion. We track 76 total achievements with an average unlock rate of only 31%. The hardest hurdle is "The One Perfect Book" which unlocks at just 4.00% across all user bases. Review snippets often mention the brutal difficulty curve and the sheer emotional weight of the narrative. Few games manage to balance such high stakes with such tight mechanical design according to our data.

PlayPile's Take

Library of Ruina is worth your time if you enjoy punishing turn-based systems and dense lore. The price point varies by platform but the 76 achievements justify the hours spent grinding for them. You will likely face failure often since only 4% of players manage to unlock the rarest trophy. Angela's story drives the experience forward even when combat gets repetitive. This is not a casual pick-up-and-play title. It demands patience and strategic planning to succeed. If you can handle losing your progress, the payoff for reaching the end is solid.

Storyline

Roland, a low-grade Fixer from a location known only as the City, one day finds himself transported into the foyer of the titular Library, a mysterious location filled with books on any subject one could think of. He soon meets the Head Librarian Angela, and after a brief scuffle, she decides to spare him and recruits him to be her guide on the outside world. Angela has a strange way of going about it though, as she sends out calling cards called Invitations to ask people to come to the Library and gives them a choice in whether they accept or decline. If the guests accept, they must survive mortal combat against the Librarians that guard the building; if they win, they can take any book they want. If they lose, they will become a book themselves. All of this is in service to Angela's goal — gaining the one "perfect" book that can make her into a human.
