Play Super Mario Wacky Worlds - Star World (demo) Online

Ever wonder what Super Mario World would look like if it took a hard left into dream logic? That’s basically "Super Mario Wacky Worlds – Star World" in a nutshell—an SNES demo that somehow got lost in time. The levels here feel like someone remixed Mario’s usual stomping grounds with a fever dream: platforms twist in impossible ways, backgrounds melt into psychedelic swirls, and everything has this playful, almost mischievous energy.

It’s short (it’s just a demo, after all), but there’s something weirdly magical about playing a version of Mario that never got to grow up. The controls are as snappy as you’d expect, but the level design? Pure, unfiltered whimsy. One minute you’re bouncing off giant musical notes, the next you’re dodging enemies that look like they escaped from a Dali painting.

If you’re into retro curios or just love seeing Nintendo’s weirdest ideas half-formed, this one’s a trip—literally. Just don’t be surprised if you finish it and immediately start Googling fan theories about what the full game might’ve been.
