I succeed in going to World 1-3, mostly. But sometimes warps into 1-1 underground with a chance of about 5%. In 1-1 of SNES with Mario, that situation sometimes happen.

I don't know why :O I hope somebody explain it. Thanks :)

Hello! I invented the wrong warp so I can tell you what you did wrong! When you do the potion zip you need to be middle to right side of the vine. You went down a couple of pixels too far to the left and ended up further into 1-1. Which is also what happens in the All-Star version!

Oh now I know I was too far left when I tried it! But thank you for the comment :)
