The sandbox game offers a lo-fi soundtrack to help players focus while building courses on a workbench. Initially, only a limited set of parts is available; players must complete challenges based on object count or marble launches to earn tickets that unlock additional parts and environments. Unlockable parts include warp portals that allow impossible physics, cannons, and race-launching parts that fire multiple marbles at once. Environments range from a fairy tale world to a space station, each providing a different aesthetic for course creation. Marble customization lets players change faces, patterns, and accessories. The Twitch integration lets viewers compete by dropping marbles into the course via chat, adding a live interactive element.
