Ever played a Mario level that just refuses to go easy on you? This one’s a brutal little slice from "New Super Mario Flash" — no power-ups, no mercy. You’ve got your basic left/right arrows, jump with up, and crouch with down. That’s it. No fancy tricks, just pixel-perfect timing and a lot of swearing at your screen.

Drop into the pipe at the start and immediately realize you’re in for a bad time. The gaps are just slightly too wide, the enemies spawn in the worst spots, and that one jump over the spikes? Yeah, you’ll be retrying that a dozen times. It’s the kind of level where beating it feels like an actual achievement, not just a checkbox.

Perfect if you miss the days of Flash games that didn’t care about your feelings.
