Dude, this game is good...not bad....
I liked the part about when Robotnik (a.k.a. Eggman) built Metal Sonic and tries to defeat Sonic the Hedgehog. It's also very fun, and I also liked the idea of making a tiny world that orbits around...well...the planet Mobius every 6 months. It's also cool that you can travel through time.
There is no Super Sonic, nor Super Metal Sonic, or the Chaos Emeralds. Instead, they put "Time Stones". How stupid is that!?!?
The Bottom Line
Well, I'd say it would probably get a 4.1 score, rather that a 3.6. it's a lot better then that. I don't know this game all the way, 'cause I haven't beaten it. I may post another thing IF I finish this game.
