Ever wanted to play Sonic but as a cat? That’s basically what this hack does—Stella the Cat replaces Sonic, and honestly, it’s kind of adorable. Same classic Green Hill Zone vibes, but now you’re a little feline zipping through loops and bouncing off badniks. The sprite work is surprisingly clean, and Stella even has her own little idle animations, like flicking her tail when you leave her standing too long.

It’s still Sonic 1 at its core, so if you’ve played that a million times, you’ll know exactly what to expect. But the fresh coat of cat-themed paint makes it feel just different enough to be worth a quick run. The physics feel identical, which is great if you’re used to the original’s momentum. Just don’t expect any new levels or anything—this is purely a character swap with some cute tweaks.

Perfect for when you want that nostalgic Sonic speed but with a little extra charm.
