Super Mario Dark World Part 2 is one of those weird, unofficial Mario hacks that flips everything you know upside down. Instead of bright, cheerful levels, you're dropped into this eerie, shadowy version of the Mushroom Kingdom—like someone drained all the color and cranked up the difficulty. The first thing you'll notice? Those familiar Goombas and Koopas are way more aggressive here.

It’s still a platformer at heart, but everything feels just... off. The jumps are tighter, the pits are meaner, and some of the power-ups do unexpected things. I remember grabbing what looked like a Fire Flower, only to realize it turned Mario into this weird ghost version of himself for a few seconds. Messes with your head a little.

If you're into ROM hacks that twist classic games into something darker, this one’s a trip. Just don’t expect it to play fair.
