A very cool selection of tricks. But I agree that the side columns of the steps are very, very disturbing. But I went to the fence. After the fence, B stands in one place and cannot go anywhere. I understand that while passing the fence - you need to make quick clicks. I love learning - But there is only one try !!! Therefore, it is unrealistic to learn. You need to be able to do this in advance. I can't get through without training.
