- TRIVIA -
Released 2 years after the original, this version can be considered as a reduced version :
* Stages : Green hill -> Spring year -> Starlight -> Scrap brain (1,2) -> Final zone.
* You have a limited amount of time per level (usually pretty tight, 1 minute is the easy setting for the first level, 35 seconds seems to be the hardest).
* Extra life boxes do nothing.
* Jumping into the special stage ring does nothing (no special stages).
* When you finish it sonic seems to have the 'you didn't get any emeralds' look despite there being no emeralds due to the lack of special stages.
