This game combines the platforming action of Donkey Kong Jr. with an educational component. The 'Jr. Lesson' addition likely incorporates math-based minigames or learning activities integrated within the game's core gameplay loop. While maintaining the main goal of rescuing Donkey Kong Sr., the added educational aspect makes this version unique from the standard releases of Donkey Kong Jr.  Nintendo's involvement is evident in both the use of their beloved character and the creation of an educational variant aimed at a younger audience. The game's Japanese-language release further indicates a focus on the domestic Japanese market.
