Spent so much time to get to the exit. I could see what to do but it was difficult for me to implement it.
Once I got to the exit no optimization was needed.
As expected, I was 2 off on my first try. Nice one!
By the way, seeing the "Silly" title, if anyone haven't tried the level "Silly" (by davidspencer6174), I would suggest you to try as that one is very interesting.
