You don't actually need x-wings to solve this one, I promise - in fact it's a puzzle I made years ago, when I first started making toroidal puzzles. You don't even need hidden sets (and I doubt you need naked sets either, but I haven't checked to be sure). It's mainly the twisty confusing nature of toroidal puzzles that makes it tricky. :) Well done on persevering! ;) Haha – I always find the toroidals very difficult to solve too!

I think it was because of the way the wavy regions wrapped around the corners as well as some regions having no values at all. I got it because I was stubborn, but there were times in the solving when I wanted to just put it away and do a different "fun" puzzle. On a positive note, if anyone needs practice scanning for X-wings, this is a good one to try. Understatement coming:
