This game is not "fun" nor "challenging", really the only challenging thing about this is trying to keep yourself from throwing your phone across the room, so apparently the protagonist is a retarded man-child with Alzheimers who cant stand up to save her life. The controls are repulsive and the physics in this game might make sense in your imagination. Overall its a waste of time and just a gigantic piece of crap.
Your apps are bad and you should feel bad about Piloteer
