Library Of Ruina Review Summary

An excellent soundtrack, original story, memorable characters, and rich lore elevate this game, but steep difficulty spikes and a weak tutorial make onboarding frustrating.

Excellent and beloved soundtrack: Players consistently praise the game's music as fantastic, beautiful, and perfectly matched to the atmosphere. The soundtrack is a standout feature that greatly enhances the experience.

Interesting and original story: The narrative is widely described as engaging, original, and captivating, keeping players invested throughout. Many find it vivid and well-presented.

Well-written and memorable characters: Characters are praised for being humanized, well-developed, and memorable, with particular acclaim for Roland and Angela's compelling development. Their writing is considered a highlight.

Rich worldbuilding and lore: The game's worldbuilding is praised as immersive, detailed, and top-notch, with deep lore that expands on the dystopian universe of Lobotomy Corporation. It adds significant depth to the experience.

Fun and strategic combat system: The combat is frequently described as enjoyable, tightly designed, and easy to learn but highly strategic. Players appreciate its depth and satisfying mechanics.

Steep difficulty spikes: Many players report a vertical difficulty spike that makes certain sections extremely challenging, often described as a 'difficulty harpoon'. The spikes are frequent and problematic.

Poor tutorial and onboarding: The beginner tutorial is incomplete, badly explained, and not user-friendly, leaving new players confused. Many mechanics are poorly introduced, causing information overload.

Confusing and cluttered UI: Players find the user interface rough, cluttered, and unintuitive, with unselectable areas and hard-to-read text. This hinders navigation and overall usability.

Fights take too long: Some battles drag on for nearly an hour, especially in the late game, and losing them forces a restart, which is demotivating. This makes the game feel tedious.

Punishing RNG: Dice rolls often yield minimum values at critical moments, and combat feels overly random, leading to frustrating outcomes. RNG is seen as punishing.

Deck-building core mechanic: The game is fundamentally a deck-building card game where players collect pages and build decks to use in combat. Deck construction is central to progression and strategy.

Dice-based combat randomness: Combat outcomes are heavily influenced by dice rolls, which can feel random and sometimes lead to frustrating losses. Players must manage the RNG inherent in clash resolution.

Turn-based card battles: Battles are turn-based and card-driven, often involving clashes and speed dice to determine action order. The system combines strategic planning with card play.

Mod support available: The game supports mods through Steam Workshop, allowing players to install quality-of-life fixes, rebalances, and custom content.

Pages and keypages: Players use pages as cards and keypages as character or class definitions. These are obtained through book burning and are essential for deck building and customization.

Performance degrades over time: Players frequently report that the game becomes laggy or stutters after extended play sessions, often requiring a restart to recover. This issue is tied to memory not being cleared, leading to increasing lag until actions become sluggish.

Poor optimization overall: Many reviewers criticize the game's optimization as bad, nonexistent, or terrible, citing heavy hardware demands and poor performance even on capable systems. Some compare it to a browser game or PowerPoint after a short time.

Frequent frame drops: Players experience frequent frame drops and unstable frame rates even on hardware that should handle the game, indicating optimization problems.

Stuttering during long battles: Stuttering and freezing occur especially during long battles, with performance degrading as battles progress.

Mouse lag after matches: After a match, mouse movement becomes sluggish and in severe cases jumps around, forcing players to restart the game to restore normal control.

Play Lobotomy Corporation first: Many reviewers strongly recommend playing or watching Lobotomy Corporation before Library of Ruina to fully understand the story and avoid spoilers. Prior knowledge greatly enhances the experience, though it is not strictly required.

Game is worth playing: Reviewers widely agree the game is excellent and worth the time and money, with many giving it a strong positive recommendation.

Great for card game fans: The game is highly recommended for fans of card games, deckbuilders, and strategy games, including those new to the genre.

Recommended for Project Moon fans: Fans of Project Moon and the previous game Lobotomy Corporation are especially encouraged to play this title.

Worth the price: Many reviewers find the game worth its full price, and some suggest it is especially worth buying on sale.

Community fair range: $15.00 - $30.00.

Game completion: 170.0h.

Story completion: 150.0h.

Session length: 3.0h.

Endgame: 30.0h.

Most reports describe a rough onboarding with a poor tutorial, unclear systems, and a slow or mediocre early game. Once players grasp the mechanics and progress beyond the opening, deck-building and combat become addictive, though a minority report fun from the first hours.

Friction: Obtuse tutorial and unclear rules; Slow or boring early game while mechanics are introduced; Confusing jargon, interface, and deck-building concepts; Sharp difficulty spikes that require deck rebuilding; Grinding and book-burning progression friction; Long, punishing fights and retries.

Project Moon Lore Devotee: Progresses through deck battles primarily for narrative and character payoff, often after or alongside other Project Moon titles. Motivation: To experience the interconnected Project Moon story, characters, music, and worldbuilding. Stance: buy.

Hardcore Deckbuilder Challenge Seeker: Builds and refines decks, studies enemy mechanics, and retries hard encounters until strategy and RNG align. Motivation: To overcome difficult tactical card battles through mastery, optimization, and repeated attempts. Stance: buy.

Grind-Tolerant Modder and Completionist: Farms encounters, replays with self-imposed restrictions, pursues full completion, and uses or creates mods to alter the experience. Motivation: To master and extend the game through grinding, completion goals, challenge runs, and mods. Stance: buy.

Performance outcomes vary by hardware cohort: the <8GB VRAM / <16GB RAM Windows group is dominated by stutter and poor-optimization reports, while the 8-11GB VRAM and Linux/Proton cohorts are more favorable; the remaining cohorts have limited or caveated evidence.

Windows <8GB VRAM / <16GB RAM: negative. Most included reviews recommend the game, but performance reports are dominated by stuttering, low FPS, poor optimization, and some launch failures.

Windows <8GB VRAM / 16-31GB RAM: positive. Both included reviewers recommend the game, though one explicitly reports poor optimization and the other gives no clear performance signal.

Windows 8-11GB VRAM: positive. Three of four included reviewers recommend it and one reports it running fine on very old hardware, while a single reviewer notes late-game stuttering.

Steam Deck: The Steam Deck experience is high-friction and effectively broken for some users. Evidence includes explicit poor Steam Deck/Steam OS performance and a refund, repeated combat crashes, launch failures after time away, severe stutter and heat even on capable PCs, and extremely small UI text. Small text alone would fit the tinkering tier, but crash and launch failures plus direct Deck compatibility complaints push the audit into the Broken range.

Monetization: The reviews contain direct positive evidence that this title is a one-time purchase with no in-game currency management or in-app purchases; card packs are described as enemy drops. Mentions of gacha, cash-cow behavior, and in-app purchases refer to Project Moon's other live-service game, Limbus Company / 084, or to the company's broader direction rather than to this game's monetization. Base-price complaints are not microtransactions. The score remains in the Fair / Pure range.

Mod reliance: User feedback mostly treats mods as optional convenience: Japanese voice restoration, Chinese page-search support, no-grind rewards, debug tools, and multiplayer convenience. One isolated report says a specific floor needs an optimization mod for stability. There is no repeated crash-on-startup or launch-failure evidence, and the 'unplayable without mods' claim lacks a specific bug, so it is treated as hyperbole rather than a vanilla-game breakage consensus.

External guides: The audit finds a strong wiki and guide dependency in the reviewed game. Most feedback describes complex mechanics, poor in-game explanations, and difficulty spikes that force players to consult walkthroughs or wikis, which aligns with Tier 3 The Student. However, the dataset also contains explicit complaints about repeatedly fighting the same stage to farm pages and about time spent grinding pages, with one reviewer recommending an infinite-pages mod to reduce that grind. Because the scoring algorithm gives strict priority to Tier 1 evidence when farming is explicitly mentioned, the final score is 100.

Sequel to Lobotomy Corporation: The game is a direct sequel to Lobotomy Corporation, expanding its world, story, and characters. Many players recommend playing the previous game for context, though it is not strictly required.

Music by Mili: The soundtrack prominently features music by Mili, often noted for vocal tracks near the end. Other composers and studios are also involved, but Mili's contribution is a major draw for players.

Long playtime and content: The game offers a substantial campaign of around 100 hours, with some players reporting 150-200 hours for full completion. It provides a large amount of content and depth for its price.

Part of Project Moon universe: The game is developed by Project Moon and is part of a shared universe that includes Lobotomy Corporation and Limbus Company. The story and setting are deeply connected to the broader franchise lore.

Korean voice acting only: The game features full Korean voice acting as the only available dub. Some players note this as a limitation, but others appreciate the original performances.
