There are a lot of places up there where it's very easy to fall back to the very beginning with a small mistake.
As I can see from the gameplay, it was difficult for me because I hadn't mastered the jump after hitting the ground properly. More precisely, I didn't notice that the height of this jump also depends on the degree of the jump. I don't know if there was no tutorial, I'm not paying attention, or I'm just stupid :)
But the game can be completed without or almost without this jump, albeit with difficulty. It's cool that the mechanics are so deep, of course, but it would have been better if they'd FORCED me to learn it.
