Sonic's partner Amy and rival Metal Sonic and the first appearance in this work. Different from other works, this work is the first time to introduce a time travel system, through the passage of different points in time, the level of the enemy, organ configuration and background will change.

We love rediscovering the history of the hedgehog with an enhanced version of one of Sonic's greatest adventures. With all the massive levels and amazing speed of the 90s, this game gives you an experience like no other on the App Store, but this classic platformer is better than ever. With crisp widescreen graphics, tight controls and awesome extras, it's a blast.
