this is my best Sonic game so far (thats why its called “ultimate”). the controls was a hard piece of work so I hope you’ll enjoy playing it 🙂
the game has 4 playable characters at the beginning and 2 secret characters to unlock. the game features a password-saver so you don’t have to start it all over again.
*password bug fixed*
