I love this game it is super fun but the only problem is that on the second boss it's really hard on chemical plants boss is really hard Doctor Eggman has slippery floor the falls off and also he Doctor Eggman is really fast that I can't even get past that stupid level even with all the characters Sonic Tails Sonic and Tails and Knuckles this game is just horrible please make this game better or I'm giving it a zero-star review I'm giving it a one because just because of the second boss
