Honestly this game is really awesome. It's a cool way to play sonic on the go. Sure, there might be ads from time to time but that doesn't affect how fun this game is. The only problem with it is the fact that the move button is a joystick. It would be a lot better if the move button was swapped with a D-pad instead since D-pads are more for 2D games and Joysticks for 3D. Other than that I have nothing else to say. Would 100% reccomend you give it a go
