The level design of this game must be studied.
So, here I am, my first visit to Zeffo. Since Bogano, I know there's going to be some backtracking in this game. So when I reach the temple and get an upgrade, I think: "Well, there was this bridge at the start of the level I can use it on, but it's kinda far away". So I keep advancing, I get one ability for BD-01, and go deeper and deeper in the level.
At this point I'm like: "There's no way I have to go all the way back for that bridge, that's insane, how come there are no fast travel points? Surely the meditation points will allow it later on." And I keep going.
Imagine my surprise, when, while following the natural progression of the map, I arrive at a central area, which connects not only to the point I wanted to reach in the first place, but to other places as well! Everything connects! And it's not just this map, every level is built this way. Like little loops.
These maps aren't small, and the fact that they managed to make level traversal so smooth and easy, without fast travel! Whoever designed this maps is a genius. This is one of the few games that got me this excited for something so easy to overlook.
Anyway. Sorry for the long essay. I finished the game already and can't wait to play Survivor.
