Honestly, I just want to start by saying this could have easily made my top 10, but I felt the other 10 games I have remaining on my ranking didn't feel right going out in this spot, while this one did.
Let's start with how this game worked, well basically it's like an open world Sonic game, where you have free range to go where ever you want for most part. Sure, there are some unlockables if I remember correctly just to access some levels, but for most part, you can explore the world at your own desire, take on mini bosses/enemies throughout each area outside of levels, and then is also some puzzle solving elements too, which I liked just for added variety.
Then it came to the story, which wasn't quite as exciting, but still left me feeling sad at the end game after the credits rolled, then the sadness turned to joy post credits. Was quite a roller coaster of emotions, especially when it comes to it being a Sonic game. Overall, I heavily enjoyed this Sonic style, and I'd gladly return to it in future when I get in the Sonic type of mood. I highly recommend giving this game a shot if Sonic is your thing
