I used to really enjoy this game, I would grind for characters and it was a bit of fun. Definitely not the best Sonic game ever but it's alright I guess, just don't expect anything too crazy.
For a mobile game this was quite addicting and I really liked playing it during some down time. Playing and unlocking other characters also felt great. Solid mobile game.
For years this was the only mobile game that I ever played probably because I'm a huge Sonic the Hedgehog fan plus I always preferred console and PC gaming anyways. Nothing much to say with this, it's just Temple Run but with Sonic characters
