A downloadable game for Windows and Linux

Keystone Library is a cozy keyboard game about restoring an abandoned magical library.

Play mini-games, earn knowledge points, and spend them to repair rooms, unlock books, welcome guests, and bring the library back to life. Each book offers a different keyboard-based challenge, including typing games, puzzles, light RPG encounters, and story moments.

The game is simple to pick up: enter the library, choose a book, play, earn points, and restore more of the world around you.

Keystone Library is currently in Early Access and will continue to expand with new books, mini-games, upgrades, guests, and library content.
