Find It - Find The Differences

You start with level 1. You get two pictures. There are a couple of differences between the pictures, and in the top you see how many there are, and how many you already got. You can click on either the left or right side, both sides count. You only have three hearts each level, which count as mistakes. If you click wrong, on something that is not a difference, you lose a heart. When you lose all your hearts, you have to do over the round.
