Alright. Posting from my 3ds in the living room.
Had the chance to go thru 2 areas using kinect. Haven't had any issues yet in terms of the kinect spazzing out. It's pretty poor lighting in my living room too.
My only complaint about using the kinect is doing the swipe motion to fire after locking on. Although it seems you can unleash the lockon any time via using your left-hand to activate the tracer cursor. So that's one way around it.
In terms of the music, the first area is your typical electronica with traces of genki rockets. But it seems the further you go, the more clearer and in tune the lumi songs become.
And in that regard, this game really is for mizuguchi fans and more so genki rocket fans. Child of Eden is quite literally the chronicle of the Genki Rockets lead, Lumi.
