World of Goo 2 is a physics-based puzzle platformer that builds on the original's quirky humor and inventive level design. Players guide goo blobs through increasingly complex environments, using gravity, momentum, and creative construction to reach the goal. The Switch version adds touch-screen controls, a new “Build-Your-Own” mode, and a collection of unlockable cosmetic skins for the goo. The game's single-player campaign features 50+ levels, each with unique challenges and hidden secrets. The Switch edition also includes a free downloadable “Goo-Lab” expansion that adds 20 extra puzzle stages and a new character, the mischievous Goo-Golem.
