I don't think it's impossible but I agree that maybe i had exaggerated(I'm not sure if it was this part that you are referring to,but, the another one is even worse) I'm gonna be updating this game on the weekend with a better difficulty curve
Based on the difference between the speed shown in the gif and the game as I played it, it seems there is a desync between frame-rate and the wall-jump time-frame (if correct, this would make it impossible on anything that can't achieve the intended frame-rate)
