hello I can't manage to make the bug to cross the pipe in level 1-2 to go to the warp zone you can help me translated by google trad

This glitch is extremely difficult, if you're not on a high level I would not recommend you to learn this before going for 4:55. But if you still wanna learn the clip, here's a video that shows the inputs: . You just have to repeat it extremely often to build up muscle memory for that, and even then you will still often miss it.

I did it and I don't even have sub 5:20, I don't think you have to be going for 455 to learn it, I mean it's fun to do stuff like that just messing around.
