Okay, so Sonic NaoSI is one of those weird, obscure Sonic hacks for the Genesis—definitely not official, but kinda fascinating if you're into fan-made stuff. At first glance, it looks like classic Sonic, but then you notice the sprites are all janky, the physics feel off, and the level design... well, let's just say it's creative in ways Sega never intended.

You'll still be running loops and collecting rings, but something about the way Sonic moves makes it feel like he's half-stuck in molasses. And the music? It's like someone took the original tracks and ran them through a blender. Honestly, I have no idea what "NaoSI" even means, but if you're into bizarre ROM hacks, this one's a trip.

Just don't expect it to play like the Sonic you remember.
