I can't help it, I keep disliking holes levels. They're so hard to me.
For that one, although noticing from the first that the symmetry isn't 100%, what told me where to go, I needed many tries
until winning. Real good level deserving by far more than a 0 as difficulty.
Agree with Tilu, here. Could give much work to beginners. It even looks confusing, right away. Not only because of so many exits, offered, but also because of restricted blocks and their position!
I liked those levels where studying a bit the configuration allows to understand the solution. For me, it deserves a 1 and could be a good level for beginners.
