Clean The Library hands you a mess: books dumped all over a multi-floor library, each one belonging on a specific shelf. You pick a book up, read the section code on its spine, walk it to the right wing, and slot it onto the matching row, then do it again until the place is back in order.
It is built for co-op, so you and friends can split floors or sections and race the clock together. Along the way you unlock abilities like Sort and Auto-Shelving and find hidden keys that grant lasting upgrades to your carry size, jump, and sprint, turning a frantic scramble into a smoother routing puzzle.
