I can't really say that I enjoyed this. I didn't care much for how you had to stay with one minigame. You should have been allowed to switch them while playing. I guess it is kind of creative. It's nice to be able to memorize stuff. At the same time, it's not something I would want from a Sonic...or Shadow game.
The music is probably the best thing about this. I guess it is pretty original. I just want more activity. It's too easy to get stuck. There were other demos before this?
