Tilt Library

A library is sliding into a marsh, and every few moves the whole floor tilts. You are a librarian pushing heavy volumes onto the right shelves, a classic box-pushing puzzle with one twist: tilts move every unshelved book downhill. Planning around the next tilt is the entire game, and later floors add stacks that slide together.

It began as a game jam entry and grew into 60 levels over about 4 hours. The art is simple, warm pink and brown pixel shelves, and the music is a single cheerful harpsichord loop. Free on itch, with a tip jar. Box-pushing fans will enjoy the clean design. The caveat: there is no undo, only a level reset, which gets frustrating in the long levels.
