Mario Must Die is one of those weird, unofficial SNES hacks that turns the cheerful Mushroom Kingdom into something way darker. You still jump on platforms and dodge enemies, but now everything’s twisted—Mario’s got this eerie vibe, and the levels feel off in the best way. Like, you recognize the classic mechanics, but the atmosphere? Totally different.

First few minutes in, you’ll notice the music’s been tweaked to something more ominous, and the usual Goombas just hit different when they’re part of a horror-themed level. It’s not polished like an official release, but that’s part of the charm—you’re basically playing someone’s creepy love letter to Mario. If you’re into ROM hacks that mess with nostalgia, this one’s a trip.
