Lets go !!!
Story: eggman is up to no good same as always.
Gameplay: This is were things have changed alot since the levels are not about running a little bit and stopping to solve a few puzzle but are rather run as fast as you can and use movement and speed to over come your puzzles which can be fun at times and than a little to hard and crazy and the bosses can be way to hard since they are all like the sonic and knuckles mushrom hill boss you know the one were you have to run and hit eggman well every boss is like this except for the final and they can get on your nerves a little bit. Finally you can play as sonic, knuckles, tails as always but you can also play as cream the rabbit who is new to the sonic series and amy who is unlockable.
Music: Not as good as sonic advance 1 but still pretty good.
Graphics: Same as sonic advance 1.
Overall: Pretty good except I dont like how it lost its old school feel but ohh well there is still some fun to be had here and is a must play for sonic fans like me.
