Funny! And I especially loved it as I solved it very rapidly, what is so rare for me... :D What a great solution. Was at 88 for a bit but the solution is really nice. I had two completely different two offs, before finding the 105. This is my favourite, in this sequence. Great fun to look for 114, here. :)
I never had 116, but did have much longer paths, first. Brilliant. My only complaint is that this one and number three are clearly their own sort of series, and feel different from the other levels to me.
