The Hourglass Twins, because it’s literally a giant hour glass, just such an interesting idea and it matched the whole theme of time running out. Every planet had something unique and interesting about it, but the one place I hated going was Dark Bramble, even up til the end. It’s just such a foreboding place that has one of the few actually “villainous” things in the game (the anglerfish) and just the whole design with thorny brambles reinforces the idea that it’s not a great place to go.
