Donkey Kong Jr.
Donkey Kong Junior was the first Game & Watch title released by Nintendo in their new Tabletop series featuring a color LCD screen in a much larger handheld format (it certainly wouldn't fit in your pocket).
Donkey Kong has been captured and chained up by Mario. Donkey Kong Jr. must rescue his papa by collecting a key from the left side of the screen and use it to unlock a chain attached to Donkey Kong on the other side of the screen. To cross the screen Donkey Kong Jr. must climb a series of platforms using vines while avoiding fierce birds, then use umbrellas to leap from heights and use balloons to move up to open a lock attached to Donkey Kong. Unlock all four chains to free papa Kong.
