Nikoli-style pencil puzzles, made by hand.
I'm in a bit of a hurry right now, I'll get back to this later if you feel otherwise, but I think there's a uniqueness issue in the lower half. I'm getting 3 possible ways to keep it all connected.
I did a computer search and there are actually 1042 solutions! Will try and see what unwarranted assumption I made when I solved this originally, and will see if the puzzle is fixable.
Haha, I guess I've missed about 1039 of them in my hurry. No worries, I really like the puzzles on here. Will get to non-critical commenting with the future uploads :P
I have fixed the puzzle at http://linguopuzzles.blogspot.co.uk/2012/04/puzzle-32-lits-3-redo.html
