This is just one of those ReMixes that I absolutely must listen to over and over...
The SFX at 31", as djpretzel says, is a nice change from the classic choices for such things...
I like how the Mix switches from the original tune at that point to a more "heavy-metal" style at that point, as well.
Near the end, at 3'05, the guitar-riff sound marks a change from the ReMix material back to Original-type stuff, with the underlying bass from the Mix accompanying it as it fades from hearing.
All in all, excellent ReMix, as other people have said, mazedude should make a few more from this game.
