New Levels and Music: The game geometry dash subzero includes three new levels—"Press Start," "Nock Em," and "Power Trip," each with original, high-energy music songs from electronic musicians such as MDK, Bossfight, and Boom Kitty. The soundtrack heightens the tension and timing-based gameplay that is key to the Geometry Dash experience.
