Donkey Kong! Regarded as the first genuine platform game, this classic made its North American debut in arcade form in late July 1981. Mario must rescue a damsel in distress, Pauline, from the titular giant ape, Donkey Kong, by jumping over barrels and avoiding other obstacles. It was later ported to the NES and released in North America on June 6th, 1986.
This game only has three levels that repeat until you run out of lives or reach the 'kill screen'. This playthrough shows all three levels for 'Game A' and 'Game B' (which has a harder difficulty).
