Or to make a cheat code to work irl.
Thinking about it, i remember when i was younger i really liked to use noclip codes on pokémon games to explore the nothing. There was a boarder where the camera would no longer change and if you crossed on the last tile the game crashed, i like to think that the "nothing" on those games are the backrooms of them, but there is only one or two levels: grassy and rocky.
