I've played it and have to say it's ok. The starring system seems really random "i could break down all the buildings, kill all the pigs and reuse all the rubble to construct a monument for my fallen comrades and still only get two stars." -Yahtzee
Personally i've been more hooked on games like Origon Trail, Mirrors Edge (no laughing) and Cut the Rope. After getting my Ipod Touch i almost immediately bought these game and more. but i did not buy angry birds.
