The game feels very close to that of the original and the choice of music feels right where it should be. Despite that though there one thing I am concerned of yet it is minor. Whenever you fly over one of the bombed areas like the turret, the sprite is below that of the wreckage but not of the other bombed areas.

All in all, it is a good game. I would like to see a name add high score feature in the future and wish you good luck on your endeavors.
