Cool pipelining.
Lol, there's also this thing where potentially, if the player went through levels 6,7,8 first, there is a weird dynamic / trap that really pays off here.
Funny one! I did study a bit the board before to start, what helped me spotting something "behind the obvious". Thanks to it, I was 2 off on first try and needed a few more tries to cut the 2 steps, that are a different way to go at a certain location. :D
