Players take control of the series’s protagonist Donkey Kong, as well as his friend Diddy Kong in certain situations, with many traditional elements of the Donkey Kong Country series returning, including mine cart levels, the ability to swing between vines and collect bananas, and the golden “KONG” puzzle pieces. New gameplay elements include levels in which the characters and foreground environments appear as silhouettes, spawning several new gameplay mechanics. In single-player mode, players can only play as Donkey Kong, although Diddy Kong rides on Donkey Kong’s back, and Donkey Kong can use Diddy’s jetpack to jump further. Multiplayer mode enables a second player to control Diddy Kong. If a player’s character dies in two-player mode, it can be brought back by using the other character to hit a “DK Barrel” that floats into view, a mechanic similar to the one used in New Super Mario Bros. Wii. To avoid problems arising from differences in the players’ skills, Diddy can hop on Donkey’s back to take on a more passive role, while his jetpack can be used to make his partner’s jumps easier. Both Donkey and Diddy can pound the ground to defeat enemies and unveil secret items.
