I had a lot of fun with this game as a kid and I return to it every now and again. I loved the Sonic and Shadow levels. The Tails and Eggman levels were alright. I never was a fan of the Knuckles and Rouge levels though. I spent most of my time on this game in the Chao Garden though trying to get myself an all S rank chaos Chao. I never got it but it was a fun time.
