Birdies Difference

Here is a new difference game in which you can prove your attention and concentration skills. There will be some sets of images with cute birdies and you will have to discover all the differences between the two pictures in each set. At a first view, the pictures seem identical to you but, if you pay more attention, you will see that they are not perfectly identical. Your goal is to gain points by discovering all the differences between them, before the time runs out. When you discover a difference, you have to make it disappear. At the end of each level the pictures should be perfectly identical. Use the mouse to click on the differences to make them disappear.
