You need to fight your way up the ladder obtaining emeralds along the way from your vanquished foes in order to face off against Dr Eggman on the Deah Egg ll. All your favorites are here: Sonic, Tails, Knuckles, Amy,….Bark the Polar Bear. There are some new faces added as well. Overall it’s fine. The music is upbeat and the animations are pleasant. It’s not gonna be played at evo or is on the level of Tekken but it’s fun.
