This is a Choco-Nilla hack of Super Mario World starring Luigi. It probably took the longest to complete, having been started in the fall of 2017 and finished in the summer of 2019. It's definitely the largest of my hacks, with 94 levels and 108 exits.
Luigi controls a bit differently than Mario in this hack. He jumps a little higher, shoots straight fireballs, and can Wall-Jump. Yeah, I know Mario can Wall-Jump in some games, but he couldn't in Super Mario World.
