Set in the great celestial library with an adorable art style, Yonda the wise librarian is the only one able to seek out the bored Great Ones who decided to abandon the needs of this universe.

At first glance, Biblinthus plays just like Tetris, where the player drops pieces of floor tiles around Yonda while rotating the screen to help said pieces fit together. The primary objective is to fill up Yonda's silver key by expanding the map, collecting various items, and advance to the next stage.

Don't be deceived by thinking Biblinthus is just a cute puzzle/dungeon crawler with Tetris mechanics. As a finely polished puzzle, the endless possibilities of Biblinthus bring out the best of each player's patience, strategy, and imagination!
