This was magic!
I started pushing blindly, going where possible, just to see where it takes me. Once I had done almost a full round around the board, I stopped to understand how to manage around target. Once clear on that, I saw that from where I was, joining the "entry" was possible: I headed there and won, on my first attempt... Unbelievable!
Really cool level. Looks totally unapproachable at first, but then you discover itβs possible to reverse-engineer the path from the finish to the start, which is a fun (though mentally quite tough) process. Nice!
