This game is great up until the 6th act. Then all of a sudden satan became a sonic developer and created the worst sonic act ever, zone 6 act 1 where it is basically 3 acts in one. which is then proceeded by an okay act which is then followed by 2 shitty boss fights. I genuinely don't know what happened. Probably a skill issue, but I had to use save states for the last 3 acts in order for them to be bearable for me. Despite the horrific ending, the first 5 zones are a lot of fun and I was surprised with how much fun I was having. 6/10
