Have you play angry birds? Is it fun to you? Are you a fan of angry birds?

I downloaded angry birds app from my iPhone, sorry for its fans but its so Boring.... So I'm gonna ask you..... Give me a reason why it became popular!!!

I don't know what you feel when you play that game but for me, its just a bunch of bitds shooting using slingshot....

And its very confusing because birds have wings, how can't they fly?
Pls give me reasons why...
