I'm having mixed thoughts about this mix (no pun intended). On the one hand, the instruments and SFX keep that creepy Egyptian feeling. On the other hand, the slow tempo for most of the song takes away from the feeling that it's a Sonic song. It also sounds a little uncoordinated.
It's OK, but it needs work in a few areas.
Also:
I hated Sandopolis Zone because:
1. Too frikken long
2. Impossible to find any giant rings
3. Scary ghosts
Yes, the ghosts were scary, at first (I tried to avoid opening that capsule as Sonic for the first few times), until you remember the jumping and lever pulling paterns for the level. But I do remember that there are at least 2 giant rings in act 1 and one in act 2. All I can remember is that you should be going higher than the game makes you think you should.
The only thing I really hated about Sandopolis was the boss for Knuckles. For those of you who never played S&K, the Knuckles story line is shorter than Sonic's, about 2 zones shorter. To make up for this, it seems the designers decided to make the bosses for Knuckles harder. If you ever manage to get the game, by the time you get Knuckles to the Sandopolis boss(who, by the way, moves twice as fast as the one Sonic fights), you'll see what I mean.
