This hack based on Sonic 1, This game plays like Sonic 1 but with the speed of Sonic 2 with CD abilities. Like CD it promotes exploration, collecting stones will reward you and also give you good futures automatically. New special stages in the future. This will not be the final build, however I intend to get it playable and presentable for the contest. Thanks for checking out my entry!.Credits:Selbi - CD CameraNatsumi - Beta testerDandaman - Beta TesterSSRG community - Feedback and Suggestions Abyss

Sonic: The One Ring is a hack of the original Sonic the Hedgehog game for the Sega Mega Drive / Genesis, created by Mercury. Its defining (and titular) feature is that in each Act, all rings but one have been removed, and Sonic cannot complete the Act without this One Ring in his possession. Thus, in each Act, Sonic must search for the One Ring that will afford him the opportunity to progress. Several alterations have been made to the game, to somewhat balance the lack of rings, and allow backtracking during the search.
