I made it to the point where i got amulet that gived me ability for two extra jumps. With this amulet i can climp to rly hight places, such as climbing reauired ones. Problem is I`m not unlocked climb rune yes, so I can overjump initial wall to such area and stuck there, cuz from the other side wall is much higher

Well, maybe you still can bypass some restricted places sometimes if random generation will be in your favor) That's what makes it interesting :)
