I went completely the wrong way to start, backtracking from the exit helped change that and I eventually got it. Tricky to me but not enormously so. Patashu's review helped me, I got there eventually after a while of thinking it was impossible. Kept me going a while, at least one 12 off! Another one where the shortest route seems longer. This level is actually really good but apparently is a copy of Hi19s level. We know what is gonna happen to james...
