Had to open a note to mark some possibi-line-ities, but getting there was a joy!

45 min for me, and they flew by, def had to write down the possible arrow/line combos to serve as an aide-memoire. Really, really enjoyed this one! Thank you!

I ended up have to do the math on paper for this one, which I usually try not to do, but it was a fun puzzle nonetheless.

Very enjoyable - I am sure there is an easier solve path than mine!
