Hi Pappapisshu,
We realise the wall jumping mechanic can be a little tricky, it definitely takes some getting used to.
One solution is to hop your way up one side of the wall. then use the fall to bridge the gap, as I know some people find this easier.
I would suggest maybe trying one of the alternate control sets for movement if you're using one specifically and seeing if that helps.
I've just downloaded and tested it myself, and it is possible I promise.
Tomorrow I'll take a look at making it easier for a new build :D
Good luck and I hope you make it through!
