It's far from being a bad Sonic game but, there are definitely some things I didn't like. Emerald abilities were pretty fun to use yes, but I felt like they didn't need to be used most of the time. The levels are actually pretty unique for the most part. Some boss are good and creative but the major bosses definitely felt kind of unbalanced in a way. Story was a bit confusing but let's be honest, you aren't really playing this game for the story. And finally the music. This game's music is so bad and good at the same time. Because they decided to make the soundtrack split into a bunch of different artists, the music is all over the place. Some good and some bad. It's quite literally a 50/50. All in all it's not a bad game, I just wish it was bit better than how it turned out.
