Looking for 294 here was GREAT FUN!
My first tries were light years away. Then I realized something and immediatelly came closer, but was still at 310+. Slowly seeing new and new ways how I can do it, I was coming closer and closer. When I got to 296, I forgot it and then found two or three 298s. After that I finally made it green, reaching the 294 path.
This was great fun. I hope it's optimal. Took me quite some time (hours, I guess) to clear it.
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
