Here I have some suggestion for the game
A/ the map could have sections eg. B.3
B/ the different flaps on the plane could move
C/ you could add a 3D cockpit that you could move around using your finger
D/ a plane with a bomb should be slightly faster but not a fast as a plane without a bomb
E/ some more buildings would be nice
F/ 3D trees
Well just some suggestions to sleep on
See you all in the skies
