This is definitely a good concept, but it needs some polishing. The way enemies can just sit in one spot while the player character is forced to fly like an airplane and only fires forward doesn't really seem to make sense and is somewhat frustrating. A bigger issue though is the companion planes. They just swarm the player and once you have 10+ of them they push you off screen making gameplay impossible.
Lastly, planes should explode on collision! It's named Kamikaze! lol
