The hell happened to my mario kart world, dawg?

Gameplay of the Mario Kart Wii Deluxe mod/fangames. it's a very impressive overhaul mid that front and back ports all tracks from the SNES, N64, GameCube, DS, Wii (duh), 3DS, Wii U, most of the switch, and even a handful from goddamn world, and Tour. as well as a load of other custom levels, ports/remakes from other kart racers.
