Ever stumble across a weird, unfinished Mario ROM hack and think, "Wait, what is this?" That's basically Super Mario Wacky Worlds—a demo that got leaked years ago, full of janky but kinda charming beta-level designs. You’ve got the usual running and jumping, but the physics feel just slightly off, like Mario’s shoes are made of soap. The Star World levels are short and chaotic, with some bizarre enemy placements that make you wonder if the devs were just throwing stuff at the wall.

It’s not polished, but there’s something fun about poking around a piece of lost Mario history. You’ll probably beat the whole thing in 10 minutes, but hey, it’s a neat little time capsule for SNES nerds.
