This is not a game, it's an extreamly realistic flight simulator. Unless the autopilot on most airliners breaks, the pilot is only there to land it. and, if you crash, you cant play again.
You can fly straight through trees, in true unity style. Add enemies and the ability to shoot. maybe some more maps, a propeller that moves (not just a black circle), and a menu. Then you'd have a game people would like. Not bad for a start.
