Very nice game and music.
The bad side is that funflow button, specially when it appears at the middle of the screen "calculating", while you are deperatelly trying to control a car, and then you click the funflow opening another tab. =/
Very good! For a next version I suggest making missions where you could cntrol more planes at once, and the enemies could have a limited perception at great distances, and also come in separeted groups... and vary the scenery. But it is indeed a very nice game!
