I like it but I agree with Diablillo: for me it's not a "trick" out of some optimization to be done. It's rather a specific route to be identified out of all the possible ways to wander in this board. I enjoyed it.
Sorry, low rating from my side. I found it unpleasant visually (am old, it's too small), and rather annoying as there is no special trick: it's just a matter of trying routes until one works.
