Except its hard and pity to avoid the big fast shoot from the ship, when the inner circle break (with no warning), the game is actually pretty good and nice (re?)use of the music. I do guess I just need to get more in the game, since its might have been that in purchase :-D
Sorry I diddent have time to soo short time to create any music, but I do think the choices you did for this game is really nice and workable, even if its have been reused from a another game, its still works nicely for me.
But if you still want me to do something, even its have been released, let me known. But I dont think its actuelly needed at all.
