This is the best and most challenging find-the-difference game I've ever played. I've played a few of these games where there are subtle differences that didn't count towards the goal, especially the games on paper, but the pictures in this game are identical besides the actual differences. Some of them are very difficult, and I did end up using malomano13's hints below, but it didn't take away from the difficulty. It killed a lot of time, and kept my attention. Awesome paintings :)
