A strange little side quest
Here is a rabbit hole for the next loading screen in Demon Castle: Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. The same trail leads to another fact: Atari's Gran Trak 10 from 1974 is recognized as the first arcade racing video game. That gives Demon Castle a little more company than it first appears to have.
