What you see here is Sonic re-imagined by some chaps from Sega of America (namely, the Sega Technical Institute). Obviously, this was a pet project that never saw the light of day. It's slow, and it's definitely different, but I dig using your health (ie rings) as an attack option. Maybe not the best fit for Sonic, but stick another character in that game and it might have been a treat. Luke Plunkett
