This is a weird little Sonic game. It's fun at its core, and there are some legitimate improvements here over the 1st game. But overall I found this game more annoying to play than Rivals 1. The level design felt more intrusive, most of the boss fights were less fun than in the first game, and the battle and tag modes that they force you to play are a major pacebreaker that bogs down the experience. Not a bad game, but I prefer Rivals 1.
