I finished the NE Lomei maze, pretty cool they have 3 levels now or at least this one had. (And I know the other two have a part in the Depths as well at least). The hardest part was getting back up to the surface... It's a small narrow tunnel to the Depths that opens up into the Maze. It proved nearly impossible to get a flying platform with control stick into that opening, and even when it worked, impossible to stay clear off the walls for that long and any touch traps the 'vehicle' against the wall. You simply can't look where you're going (up) with a control stick.
So back to rocket balloon, which flies straight up (if launched straight) but doesn't last to the top. Adding fans to the bottom finally worked. Still hard to get 3 fans in the right place and flush to the underside of the gondola to get it to launch straight up. Overall well over a dozen attempts and an hour of trying things to get back out. Nintendo certainly made 'no fast travel' 10x harder in TotK. Everything is designed to have you race / glide down and teleport / ascend back out.
I'm finishing up the Shrines in Akala, the NE corner. I visited the now pretty useless horse god, dragged a Korok to his friend by gluing him to the yoke of a horse, delivered by a Moblin. Then abandoned the horse again, too slow. But might try the horses some time to see how much 1hp is in TotK, how much can a horse pull. And can you make a team, multiple horses pulling a train of carts :)
Currently I'm briefly back in the Depths, decided to take a little shortcut detour underground by two forge constructs, to get some more Zonaite converted to crystalized charges. And it does seem everything has reset now. All camps are full again, all resources are back including poes, no trace of any light blooms I left behind. The only thing that's permanent are the crumbly rocks you removed. Anyway nice to have no day/night cycle and no rain nor heavy fog for a little while! Much easier to see down here lol.
