Alright so I know this game got hated and I also sort of hated it. But it's still a game.
Anyway let's talk about the game gameplay wise. The game is GLITCHY. Sonic Team did have enough time to finish the game so they released while it was still broken. Which caused a lot of glitches. The story didn't feel like this is some thing the Sonic Team did. In fact it feels like Telltale games did the story or something. The music was really cool except for Mephiles. And the game added that weird girl Elise. Which made a weird balance for Sonic. And ALL THE LOADING SCREENS ARE INSANE! If you're one of those guys who likes glitches games then get this one. If you don't don't buy the game.
