Given that I found this game on a site for kids, it shouldn't be this difficult... :)
Lineum is a puzzle game where you have to draw a single continuous line to turn all the tiles green. In the "hard" category (there's also novice, easy, and normal), level 16 looks like this:
I can't seem to figure this out. If you ask the game for a hint, it tells you where to start:
...but that hasn't been terribly helpful, either.
Note that it is possible to flip a tile twice if you go through it with perpendicular lines, and all the other puzzles in the "hard" category make use of this.
I can't find any walkthroughs or solutions to this game. Is there someone smarter than me out there who can figure this out?

I found the solution. There's an Android game called Unium which is pretty much identical to Lineum (no idea which came first, but I'd guess Unium), and a kind soul has posted solutions to that game.
(One problem I was having is that the starting point hint provided by Lineum is wrong.)
