For a while the 77 looked impossible, but it was the fact that it seemed impossible that helped me find the answer. I like the solution here, but it’s clearly unintended. If this was the intended solution it would’ve been nice for the false ones to feel a little more possible, and add more of a challenge.
ROFL! I did about 5 tries, and was so far away... Out of confusion, I decided to do a very basic route, even if longer, just to see if it brings me with new perspectives, and... It was the winning route! Unbelievable... :D
