Well actually KH3D was less time travel and more going to worlds that were asleep so that they were constantly going through the same few hours again and again. At least that's what seems like to me.

by then of course you have these dead little shits who get dragged in by Mr Angel dick on the right there. (I love these guys really and I really hope we get to go to their world in KH3)

But yeah, KH is convoluted and over complicated why do I love this franchise?
