i got there but i feel out of bounds due to the pole and i rage quit. you can do it on the ohter sideby wall jumping then getting on that block. then parkuor ur way to the next part.
There's no two ways about it - this is the hardest jump in the game. You can easily get to the bottom dissolving block by wall jumping off the pole to the right, but getting to the 2nd block is tricky. I find I do it best if I don't even think about it
