I'm honestly glad my game always crashes whenever I try joining this exact servers, because I'm pretty positive they got the rules piled on a deathmatch server.
It took me 2 weeks to learn it lmao, when i finaly learned it i made a tutorial on how to do it because nobody else has, if you wanna see that then you will easily find it in my channel
It seems a lot harder to do when theres a lot of people in the area, like when im out in the middle of nowhere i can easily hit jumps without even trying, but when theres people around it just doesnt let me
