"Jumpman" was the original name used for Mario in the 1981 arcade game Donkey Kong, which featured several elements (such as the ladders and levels aspects) that would appear in Jumpman. Randy Glover has stated that Donkey Kong was the original inspiration for Jumpman, although it is not clear that the naming commonality is anything but a coincidence.
