The walljump is not buggy, you can only walljump when you are wide. That's what 2-1 and 2-2 teach you. You can climb when tall, and slide + jump when wide.
I am aware. The problem is that it sometimes just didnt work
what do you mean by didn't work?
sometimes i had to spam space multiple times for it to work
never happened to me before, what OS are you using?
windows
