About this game

Help a tortoise librarian build a tower of books by tapping to drop each swinging volume the instant it lines up with the stack below. Perfect drops build combos and earn aurora energy you can spend on crucible powers (keys 1, 2, 3) to widen the base, slow the swing, or lock a book in place. Miss the overlap too many times and the tower topples.
