Very interesting. I went straight from 45 to 41 so I missed looking for the 2 save, but I will say that the 41 path is extremely counterintuitive and fun.
Woooow! This was so hard for me, to see. Even finding 43 wasn't fast and easy, but 41 seemed near impossible, for a while. :)) And even when I got it, it felt so ''unnatural'', lol. Of course it's not, it's just that I'm not wired in such manners of thinking. LOL
GREAT puzzle! :)
