Ever thought Super Mario World was too forgiving? Yeah, me neither—until I tried this brutal demo hack. It's the same colorful Mushroom Kingdom you remember, but everything's out to get you. Piranha Plants lurk in places they shouldn't, jumps require pixel-perfect timing, and those Koopas? They've got a personal vendetta.

First five minutes in, I lost about 20 lives just trying to clear the first few platforms. The level design is devious—hidden blocks where you'd never expect them, bottomless pits disguised as normal gaps. It's like the original game got possessed by some sadistic ghost.

If you've played SMW so much you can speedrun it blindfolded, this might actually make you break a sweat. Just don't throw your controller.
