When I discovered its existence I was very excited about a 4th entry in the classic Sonic series, but after I started it, I abandoned the game shortly after because how unfun it felt.
Years later I came back to it and finally beat it, but my impressions about the game didn't change so much.
Very dull, souless Sonic game.
As I played it on PC I wasn't aware this game was originally designed for Mobile. Once I knew that, it became more clear why it is like it is. So, for a mobile game, is ok. But still is very far from the Genesis titles' quality.
