Hey!
Maybe try the new update!
At the part of the story, where you are now, is a new checkpoint and a new Information sign!
I hope, you can do it, now! :)
(Sorry, I haven't known, that this part is so difficult!)
P.s.: In the new update it's also possible to sprint with "shift"!
It really helped! Just with the explanation I was able to do in in no-time, compared to my last video. And the running was also a very welcome update!
This game is only getting better and better!
