Super Mario Dark World Part 3 is one of those fan-made SNES hacks that takes the classic Mario formula and cranks up the difficulty—like, way up. You’ve got the same tight controls and familiar power-ups, but the levels are packed with brutal enemy placements and some seriously devious platforming. The first time I played, I lost like five lives before even reaching the first checkpoint.

It’s not just hard for the sake of being hard, though. The level design actually feels thoughtful, with secrets tucked in weird spots and some clever twists on the usual Mario mechanics. If you’ve ever thought the original games were too easy, this’ll scratch that itch. Just don’t throw your controller when you miss that jump for the tenth time.
