It's an open World Sonic game that isn't good. You can beat levels & collect keys but that isn't the primary focus of this game. This game is more RPG. You have to power up your guy find said hearts or whatever item in the said World to proceed & continue with saving said friends. Ex: Amy: you need to give her like 13 hearts. The World is pretty big, so you'll be walking around a lot to find them etc. You can't go to a said location in this by highlighting an icon & press a button.
