Sonic Whirlwind is a Platform game based on the Sonic games like sonic 1-3 and newer games like sonic rush. The Engine is Sonic Worlds 0.3 made in MMF2. Also some game modes new to sonic like character boss attack, where you can battle playable characters and some npcs as if there where bosses, like in sonic sonic adventure 2, and even some old thing like tails following you. By the way don't bring up the old demo cause I know it sucked.
