So, this is one of those obscure SNES demo cartridges—basically a weird little slice of Mario history. You get a handful of levels that feel like early prototypes, with some odd quirks in the physics and a couple of unfinished-looking platforms. It’s not a full game, more like a "what if?" version of Mario where things are just slightly off.

Jumping feels a tiny bit floaty, and some of the enemies move in ways that make you go, "Huh, that’s not how Koopas usually act." But there’s something charming about it, like digging through old game dev notes. If you’re into retro curiosities, it’s a neat five-minute peek at what could’ve been.
