I don't know whether these are known or not. Super Sonic keeps Sonic's pallette when underwater. Is that normal? Also, Septic Slide's music glitches sometimes, but it sounds awesome when it does. Also in the level, the screen flashes white when the music changes. I like the lack of signposts at the end. Makes it look like he really is going off to the next part instead of distracting the player with a big sign. EDIT: Also, forgot that the Ball Hog just exploded instead of just releasing bombs in RRZ.
