Cut The Rope

Game description:

This cute green creature with big eyes is your new pet! His name is Om Nom and, as you can guess by the sound of it, he really likes to eat. Actually, he is hungry all the time. And his favorite treats are candies. You will be getting them for him in a rather unusual way. They will be hanging on ropes at different height and you need to figure out how to cut those ropes so that the candies fall right into Om Nom's widely open mouth. There will also be other factors, both helping you and getting in your way. The game is based on realistic physics, so this is going to be interesting!
