The demo released along with Phantasy Star Online still has these shoes (likely before the endorsement deal had been fully inked).

Rouges original name was "Nails" (possibly to rhyme with tails and/or to contrast with Knuckles) and her design was much different ◊.Possibly scrapped due to being too scary or the idea of rendering one eye on shadows conjoined eye to not look believable. Shadows original name was "Terios", which means "reflection of" (but in promotional material his name was Dark Sonic), along with several early designs for Shadow, some can be found on the page image above, show him missing an eye, and at one point, he had black eyes with a singular red pupil, Some designers with a more muscular body, a design with sunglasses and a head visor, a design where he has hair on his forehead, one with a scratched out eye wearing an ominous cape and holds a knife, and some designs similar enough to Sonic that the game's plot point of Mistaken Identity is much more justifiable.This concept seems to be a proto version of what would become Sonic Rush Series. An rumored earlier premise of the story was Shadow and Rouge were from another dimension and destroying the world, and it would be up to Sonic to stop them.

The alternate stages would be branching, a feature that would return in Shadow the Hedgehog. Originally the game was only going to feature Sonic, Knuckles and Eggman as playable characters.
