The game features environmental effects throughout some levels, which include fog, rain, and thunderstorms. Some levels feature different mechanics and settings, such as underwater sections, riding a mine cart, grappling onto vines, and "honey" levels which feature sticky surfaces.[1][2] As with its predecessor, the game features barrels that will propel the player in any direction they are facing.[3] Aside from checkpoint barrels, some give the player temporary invincibility or an "animal friend".
