Play Super Mario World (Beta) Online

Ever played Super Mario World so much you could draw every level from memory? This beta version is like stumbling into a weird alternate universe where everything’s just… slightly off. Yoshi spits fireballs instead of eating enemies, some levels have bizarre unfinished layouts, and there are these creepy unused enemies that look like they escaped from a different game entirely.

It’s not just broken—it’s weirdly playable, like someone took the Mario we know and remixed it in their basement. The controls are still tight (thankfully), but you’ll catch yourself double-taking at stuff like floating question blocks in places they shouldn’t be. If you’ve ever wondered how much polish went into the final version, this beta makes it painfully obvious—in the best way possible.

Honestly, half the fun is spotting the little differences, like how Bowser’s castle has this janky prototype version of the spinning fire bars. Perfect for when you’ve 100%’d the original and need a fresh hit of that sweet, sweet Mario nostalgia—but with a side of "what were they thinking?"
