Super Mario Bros. - The Castle on SNES is one of those weird little fan-made hacks that popped up back in the day. You're still running and jumping through classic Mario levels, but someone went and remixed them with a bunch of castles—like, way more castles than any reasonable plumber should have to deal with.

The physics feel a little off compared to the original, and some of the jumps are just mean for no reason. But if you've played the official Mario games to death and want something slightly different (and slightly janky), it's a fun curiosity. Just don't expect Nintendo polish.

Honestly, I kept playing just to see how many ways they could reskin Bowser's castle.
