Kaizo Mario World 2 is one of those brutal Mario hacks that makes the original Super Mario World feel like a warm-up. Right from the first level, you're dodging instant-death traps, pixel-perfect jumps, and enemies placed just to mess with you. It's the kind of game where you'll die a hundred times before figuring out the exact timing for a single jump—and then realize there's another nightmare waiting right after.

The level design is cruel but clever, forcing you to learn patterns or get creative with power-ups. I still remember the first time I saw a P-switch drop onto a conveyor belt—pure panic. If you're into masochistic platforming or just love seeing how far Mario can be pushed, this one's a classic. Just don't throw your controller.
