i loved the atari style of art and mechanics, but i think you have 2 games in there
with some polish and adjusts on the physics, i can see a game were you have to fly close to the ground and hit targets while avoiding crashes; and a game where you have to loop on the air to score points.
the two mechanics aren't really connected in any way, besided that you HAVE to do one then the other right now...
great concept, and could work really well - even keeping both aspects, but integrating them more, in some form
