Donkey Kong Country 2: Diddy's Kong Quest is a 2D side-scrolling platformer in which the player controls either Diddy Kong or his childhood friend Dixie Kong through 52 varying levels over eight different worlds. The main objective of the game is to rescue Donkey Kong from King K. Rool. The game features a wide number of enemies, which include land-based reptilian Kremlings, rats, porcupines, bees, and vultures. Enemies in underwater sections include pufferfish, stingrays and piranhas. Each world culminates with a boss fight, which is required to be defeated in order to progress to the next world. Similar to its predecessor, the player-characters may neutralise most hostiles by jumping on their heads, cartwheeling through them, or throwing a barrel at them. When hit by an enemy, the active character leaves the screen, thus control will switch to the other character. The player can reclaim their partner from marked DK barrels throughout the game. If both characters die, the player will lose a life and will restart from either the beginning of the level or from the last checkpoint, which comes in the form of a star-painted barrel. If the player loses all of their lives, the game will end.[11][12]
