Looks great! I really like the overall look of the game and there seems to be enough platforming, just like there are enough speed sections. Switches, elevators and things like that really remind me of S&K... I like that! In fact, Sonic games IMO were always more fun in the second playthrough, since you get a really great sense of satisfaction and accomplishment, when you get very smoothly through a level (obviously by remembering the obstacles and such)!
Can`t wait to actually getting my hands on this game. Hopefully it won`t be too long...
(I`m not really surprised, that there is no "Yaaaaaaaaaaaay"-shouts for SuperSonic being in-level-playable (since that was something, that seemed to be eagerly demanded by all the "fan-boys), because I got used to it, that the first thing that is being made, when a new Sonic-video or -feature is revealed, is bashing the look of the character model or something along that line)
