On first try. I studied a bit before to start and saw that only one side gives some free room. Out of the 3 others, one has an obvious shorter path and the two others forced routing. On my opinion, it's too easy for category "junior high".
HAHAHHA. Fun level. :)) I got it 1st try, but didn't play very fast. There ARE places where one can mess up (especially beginners). :))
What I like most here, is the looks. It really does look beautiful. Like some mandala. :D
