Final project purpose of the game

My game takes place in the sky with a airplanes. You control one of the planes and goal is to get to the other side with out hitting any other plane. If you hit a plane you loose and get sent back. If you hit the water you loose and you also get sent back.So you have to make it to the other side without hitting into water or other planes. If you get to the end you go to the next level. Use the arrow keys to move around. You get 5 points for every level you complete.
