Liked the look and sound of the game but wow, very touchy. There is no feedback on speed or visual indication if you are falling slow enough, whether your lateral motion is low enough, or whether you are straight enough to land. The only way to know is if you blow up. Which you will. A lot. It was fun for about 5 minutes but then I deleted it out of frustration of not knowing what I was doing wrong when I crashed or right when I did not. Beautiful game, but mechanics and feedback need some work. Also, as a side note I originally launched this app in landscape mode and had to rotate my iPad Air to portrait at which point the game was not rendering fully on the screen. Killed app and restarted in portrait and it fixed the problem.
