I was giving 5 stars of "use of theme" to every game I was playing. Now I've got to change it all, shame on you! Haha, anyway really good graphics style for the theme. I didn't quite like the lack of variation since there are only 3 plane types but overall enjoyable gameplay. Adding asteroids/satellites, going faster than planes, that you need to avoid at the same time could be a great variety addiction. Really polished game, well done!
