Cant tell if bait or serious for the BBkart. Would be fun but I dont think it would be easy to code at all.
Yes I'm serious about BBKart, they intentionally added it to the game, coded as well (the april fools one), just a little gimmick.
They said that they're actually going to add it as an actual thing but it's nowhere to be found, or maybe hidden too much, or maybe unused.
