Wow! I finally solved it! It was hard for me and finding the winning route was pure luck.
I can give the trick that made it for me: I changed side. I then won on first try, like the new perspective was the key... LOL
Gorgeous!
I think it belongs to ''rated''!
6 stars!
It was really hard to see, how to even touch the exit. My first touch ended in a smaller ''step overdoze'', LOL. The next one was then 200 sharp. A very satisfying touch! !!
