Boris is one of those weird, charming SMW hacks where someone took Mario World and just ran wild with it. You're still jumping on platforms and dodging enemies, but everything's been tweaked—some levels feel like they were designed by someone who had too much coffee, in the best way. The physics are a little off, the sprites are janky in places, and honestly? That’s part of the fun.

First thing you’ll notice: Boris himself (whoever that is) replaces Mario, and the overworld map looks like someone scribbled over the original with crayon. Some of the jumps are way tighter than vanilla SMW, and there are a few enemy placements that’ll make you groan—but in that "okay, one more try" kind of way. It’s not polished, but it’s got personality.

If you’ve played a bunch of Mario World romhacks, this one’s worth a look just for the sheer chaos of it. You’ll either love it or rage-quit by level three.
