Donkey Kong Jr. is the sequel to the immensely popular Donkey Kong arcade game, and the NES version ported the game near exactly for play at home. Players assume the role of Donkey Kong's son, Junior, set out to rescue his pop from Mario the kidnapper. The adventure takes players across four different locations that put Junior's jumping and climbing skills to the test. If Junior grabs onto a single vine, he can climb up slowly or slide down quickly...grabbing two parallel vines will giving him faster climbing abilities, but his descent speed is slowed down. Mario continues to send enemies down the vines...but Junior can take these guys out by plucking fruit out of mid-air and sending it down to nail 'em on the head. The game features all four of the challenges that were introduced in arcades two decades ago.
