Super Mario Bros. Lost Levels Walkthrough Part 2: Castle Of Lies

Even when I took the right path it still buzzed me, leading to lots of confusion. Why was that anyway?

Also, to add on to what I said in the beginning about World 9, from what I heard, you ONLY have to beat the game without using warps. But just in case it detects that I am quitting the game and coming back (Like, if it may be a requirement) I'll be savestating at the end of every part and only then so I can resume there as if I didn't turn off the game.

Enjoy!
