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.
Note: The transition from 5-screw to 3-screw cartridges in Nintendo Entertainment System (NES) games was primarily a cost-saving
measure implemented by Nintendo during the late 1980s. This change occasionally coincided with updates to other aspects of the game's
packaging, including the Universal Product Code (UPC) and/or a color change to the Nintendo Seal of Quality (SOQ). Not all NES games
underwent a UPC change during this transition and many retained the same UPC across both cartridge designs.
