Play Super Mario the Lost World Online
Jump through weirdly shaped levels tossing fireballs at misplaced enemies, though the framerate stutters like a tired plumber. It’s got that rough Flash game charm if you’re into janky Mario nostalgia.

Okay, so Super Mario the Lost World is one of those countless Mario fangames floating around, but this one actually tries to do something different—sort of. It’s got these "unseen" levels, which mostly means weirdly shaped platforms and enemies in places you wouldn’t expect. Not exactly groundbreaking, but hey, at least it’s not just another lazy rehash.
Controls are simple—arrows to move, space to shoot fireballs—but fair warning, the game chugs a bit. Like, you’ll jump on a Goomba and the frame rate decides to take a coffee break. Still, if you’re nostalgic for Flash-era Mario clones, it’s got some charm. Just don’t expect anything polished.
Honestly? It’s a decent time-waster if you’re bored and miss that old-school jank.
