Library of Ruina memes originate from the rich, complex world of Project Moon’s tactical deck-building game. Fans primarily focus on the game's intense emotional narrative, its iconic 'Vertical Difficulty Curve,' and the memorable soundtrack by Mili. Popular meme formats often involve the protagonist Roland’s dry wit, Angela’s existential struggles, and the various 'receptions' of guests who enter the library. These memes have become a staple within the 'Project Moon' community, serving as a humorous way to cope with the game's brutal difficulty spikes and tragic storylines while celebrating its unique aesthetic and lore.
