The game's story is that Dr. Robotnik has flew to another island, and it's up to Sonic and his new friend, Tails, to stop him. The doctor has found 7 special gems and they grant him ultimate power. The player must take him down. The gameplay is similar to the first Sonic the Hedgehog game. The player can run, curl up into a ball and jump, and perform a new move, the Spindash. The spindash is a move where Sonic can curl up, gain energy, and roll at high speeds. At the end of the game, the heroes can be seen flying in the air. The game has variety in its gameplay, with a flying section in a plane level.
