Game App

[rainebm1185]

I can't remember the name of the app I played all the time. It was about flightless birds (please don't suggest Angry Birds) that went up and down on hills. The way you got them to fly was aim down right at the valley to shoot them higher in the skies. The trick was getting fast enough to outrun some tornado or something coming up behind you. Anyone else play this game and remember what it's called?

I lost it when I got my new phone and can't remember the name to look for it again.

Thanks for any help
