literally worse than the original in every way. the two character gimmick is so painfully forced, the levels are worse than the originals, they added new zones for no reason, they removed the twist of finding emeralds in the stages, completely replaced the final boss, added a knockoff doomsday zone at the end for some reason, and the inclusion of super sonic ruined the challenge of the bosses. do not play this, play the original master system version.
