Infinite Mario HTML5 is basically a love letter to Super Mario World—you know, the one with the cape and Yoshi? Every time you start a new game, it cooks up a fresh overworld map with branching paths, hidden shortcuts, and levels that feel just unpredictable enough to keep you on your toes.

The controls are dead simple: arrows to move, 'S' to jump (or pick a level on the map), and 'A' to sprint or chuck fireballs if you're lucky enough to grab a power-up. The levels nail that classic SMW vibe—floating platforms, secret exits, even those annoying little spinies that always ruin your day. It’s not just random for the sake of it, either—the generator actually makes levels that feel like they could’ve been in the original game.

Honestly, half the fun is seeing what weird mashup of enemies and obstacles the game throws at you next. One run might give you a brutal gauntlet of hammer bros, the next a breezy sky level full of coins. You’ll probably die a lot at first, but in that nostalgic "one more try" way. If you’ve ever wanted infinite Mario World levels, this is as close as it gets.
