Exit touch and optimization are both great! holy hell the last 2 is a great trick. I'll never forget this. Ok it takes some time to analyze. Not bad at all. Surprisingly unique structure with traps in it. This needs to be ranked. Optimal 2-off 4-off 6-off 8-off all over the place and they all make sense. Is the final path "logical"? I don't really know. Logical but easy to miss. why... Solve #4000
Goddamn long journey
