Sonic 3D Blast is an isometric platformer/collectathon by Traveler's Tales for the Sega Genesis/Mega Drive. While visiting Flicky Island, Sonic notices that the Flickies, his small, feathered friends that can travel between parallel worlds, were captured and turned into badniks (the robot enemies of Sonic) by Dr. Robotnik in his never-ending quest for the Chaos Emeralds. Seven levels separate Sonic from the final showdown with Robotnik.
the0nlykyd collects all Chaos Emeralds and gets through the final fight, thus getting the good ending, in record time.
