If you mean fast by how long it takes to finish the game then no.
If you mean fast by how fast the characters move, I can say this, I was running so fast that I didn't actually have the time to make sure that I Knew where I was. There are also some special added jumps and power boosts in the game the make Sonic go incredibly fast, and as I said before, I have no idea what Blaze the cat can do since I never even played as her. The bosses in this game do have an odd twist to them, they are kind of in a 2-D/3-D style you know, where you can move in a 3-D place but only go along vertain parts of the 3-D thing that gives it a 2-D feel.
