The big draw of this DLC is the inclusion of more playable characters in the form of Tails, Knuckles and Amy. I was curious as to what they would do to differentiate them from Sonic. The main difference in comparison to Sonic is how each of their jumps work, where Tails can fly, Knuckles can glide and Amy is rocking a triple jump and float after the third jump. While that is the biggest change I can name, there are other changes, such as Tails being the only one to not have a homing attack, and they are not as fast a Sonic. The story content is what I hoped, how the base game would have ended, as the final boss is much more challenging and interesting than ending the game with a sh'mup. Speaking of challenge, this is the most challenging Sonic content in a very long time. The last one I remember having a hard time with is Sonic Advance 2. The Master King challenge is main reason why this game is really challenging, on top of making parry harder to use while on the hard difficulty, so I can only imagine how hard this is on extreme.
