Actually not bad...
Remixing the audio for this game can be hard to do without butchering it, that being said, it shouldn't take much to clean this up and make something downright awinspiring. The fact that you even got close to that should be isperational.
(It might be noteworthy to mention my bias on this one, this is the only game I've ever played more than 10 times. (200+))
