Trivia

 * This was thought to be a prerelease preview of Sonic Adventure.
 * Sonic, Tails, and Amy also appear as ending cameos.
 * This is the only game that uses the partial ring system and the second to use centiseconds for the time display.The first was Sonic CD.
 * This is the first Sonic game that has each level play through a day/night timeframe (i.e.: Act 1 in the day, Act 2 in the night, etc., though not exactly like that). The second game to do so was Sonic Unleashed.
 * It is believed that sprites from Sonic's role in the unreleased Sonic Crackers were the basis of Mighty's in Knuckles' Chaotix, as their sprite sheets are mainly identical.
