It is a fair game all together, with great gameplay experience and an average plot. It has good-ish graphics and multiple features of customization. Unfortunately though, it is suprizingly short. All storylines were beatable in roughly five hours, cutscenes and credits included. Controls need work in certain areas when it expects you to move fast. It also has a LOT of collectables earned mainly at random in its limited stages, so you'll be repeating stages ig your not lucky. Its last main flaw is that every once in a while it jumps from easy-medium to crazy hard without real practice. All in all it is one of those games that is really fun even though it kind of rips you off at certain points, making it a good game - for all five hours of it. So remember: it does't last long so rent it unless you can work with repetition. Also, for those with reference to it, gameplay is most simalar to Sonic and the Secret Rings.
Note: this review MAINLY focuses on the plot of the game and needs more looking into on extras. (although they probably won't that long if the main deal is that short)
this game was a good game until........ 8 hours later i beat it. Now i know it should take longer than that. This game is one of the better sonic games as far as game play so if you like the sonic series than get this game.... just keep in mind that it won't take long to beat.
