Is it like a bug or an evolution thing

Do you mean the Any% specifically ? One advice i'd give you is to experiment yourself ; usually when you dash into walls with a angle you are going to go farther. It also have the benefit of going through doors faster, if you aim for the door you'll be mostly stopped, but if you dash to the side of the door first you won't be stopped and still go through. The very best advice is still : Do it a lot. Get a feel for it. Good luck for your runs :)

Absolutely, well put Patatoes! The only thing I think can make it go farther is getting lucky with debris, I've seen it happen but it's always on accident.
