As most would be able to gather, there is no actual time travel in Unwound Future. But the fact that it's all an elaborate set that was built deep underground with the intention of hiding a super mecha fortress is just as jaw dropping. I knew something was up from the beginning, but I just couldn't figure out how to explain it as anything BUT time travel. I thought maybe instead of a time machine they created a teleporter, or perhaps just a gateway to another dimension. When it was revealed that the clock store is actually a huge elevator I think I caught myself mouthing "cooooool".
