by Mario, has been entrusted into his care. However, his son, Donkey Kong Jr., appears and attempts to rescue his father. Mario takes his keys and places them in the building he fought Donkey Kong in. To stop Donkey Kong Jr., Mario unleashes several circus animals, but Donkey Kong Jr. escapes them and makes it to Mario’s headquarters. The two face off but the building begins to crumble, causing a recreation of Donkey Kong's climatic scene. Donkey Kong Jr. saves Donkey Kong and the two set off together. Development During Donkey Kong’s development in 1981, Shigeru Miyamoto's team had come up with several ideas and full complete levels that wouldn't really fit into the game due to the various constraints. His team eventually began fleshing out these concepts, and these designs evolved into something all their own. The process was so far along, with even entire stages conceived, that one of the team members suggested they start working on another video game. The conversation happened around the same time that Nintendo wanted another Donkey Kong coin-op to capitalize on the original's fame, giving Miyamoto the perfect opportunity to further explore his newly established franchise. Originally, Miyamoto wanted the new game to star Donkey Kong himself, but there were problems with the character's massive size. He wouldn't be maneuverable on the screen, so a new star was needed. The change brought about a new hero and drove the narrative in an entirely new direction. They ultimately came up with the idea to make a smaller Donkey Kong in place of Mario who would be the son of Donkey Kong. Since they still wanted a big Donkey Kong on top of the screen, they came up with the plot of Mario capturing him after the events of the first game. Versions The order of the levels is different in different territories. In the Japanese version, the four levels appear in 1-2-3-4 sequence and then repeat, just as with the Japanese release of Donkey Kong. In the US version, the order is 1–4. 1-2-4, 1-3-4, 1-2-3-4 and then 1-2-3-4 from then on. Kill screen Donkey Kong Jr. has a kill screen at level 22. Due to the level counter only having one digit, the counter shows numbers 1 to 9 in levels 1 to 9, seven blanks in levels 10 to 16, and the letters A to F in the levels 17–22. The
