Can you hit them all?
There's no sound? I'm not hearing anything. The visuals aren't bad, but nothing to really make me think of anger or aliens. If I did feel like an alien, I have no indication at all what I'd be angry about. Sometimes when I pull the ball all the way back, it just drops or gets caught on the edge of the screen. And what's shooting the ball? It's good to know you *can* make an angry birds style game, but without something new and interesting, what's the appeal?
