A strange little side quest
Even a quick game like FNF x Colorbox Mustard sits on top of decades — and sometimes centuries — of ideas. Spacewar! appeared on MIT's PDP-1 in 1962 and became one of the earliest influential computer games shared among programmers. And then there is this: Pac-Man went on sale in 1980, and its creator Toru Iwatani famously linked the character's shape to a pizza with a slice missing. That gives FNF x Colorbox Mustard a little more company than it first appears to have.
