It sounds like you're looking for a or creative take on "Super Mario 2D World Deluxe" for PC, since no official game by that exact name exists for download. I’ll craft a short, imaginative story around the idea of discovering such a game. Title: The Secret Pipe

Leo sat in silence. Then he smiled. He didn’t need proof. Some pipes are meant to be secret. Moral of the story: The best downloads are the ones you can’t keep—but never forget.

Leo was a Mario fan through and through. He’d played every official release— Super Mario Bros. , New Super Mario Bros. U Deluxe , even the fan-made rom hacks that crashed more often than a Goomba on a cliff. But one rainy Tuesday, while scrolling through an obscure retro gaming forum, he saw a post that made him freeze.

Then the game closed itself. The folder on his desktop vanished.

“You weren’t supposed to find this. But since you did… thank you for believing 2D Mario could still be new.”
