this is my simple suggetion for next update probably can support crappy devices.  

      let us create our own map directly on the game since downloading UNITY and organizing the android SDKs and some stuffs is a big hussle.

      also realistic enviroments for high picture quality such as grasses, clouds and etc.. 

        please have a limit on when we fly high.. limit it upto few kilometers high. when the plane starts to go higher at the point the air is so thin and almost non existent the engine will fail and plane will stall.

        and also multiplayer update for android users.
