This medium level requires some thinking before you play it, there should be no problem if you work out your plan in advance.
For those who are stuck:
Is the way you see at the beginning the only way to get to the finishing point?
If it is too direct, I will edit it
heh, this level looks just like zipper, and you fail it for the same reason: just because there's an easy way through it, you don't have to continue with it the whole time
