Game Description: In Donkey Kong Jr., players take control of Donkey Kong’s son, who must rescue his captured father from Mario, the antagonist for the first and only time in the series. The gameplay involves climbing vines, jumping across platforms, and dodging enemies like Snapjaws and Sparks while collecting keys to unlock Donkey Kong’s cage. The game reverses the roles from Donkey Kong, making the player the rescuer instead of the pursuer.
