And I'm starting to like Mercury just as much as I liked Venus, before this version of the game came out. Mercury has a different concept attributed to him, differing from Venus (assuming this based on the song ToeWalker that's consider as his theme).

I'd try to explain what I'm thinking but my brain's not braining and all I could say is that listening to both Venus and Mercury's themes, you can tell there's a difference in concept.
