Finished the Edo chapter last night. So I'm now about halfway through.
Wild West chapter I was hoping would have a bit more meat on the bones but as an optimization puzzle at the core it was kinda fun. I definitely goofed up on some of the tasks and I was checking a FAQ for the SNES version and it looks like I missed a secret room somewhere. Ended up having to deal with the boss and about 4 goons which made for a bit of a tense fight and several restarts.
Edo chapter is definitely the crown jewel of the game so far. It took me a good while to wrap my head around the layout of the castle but once I did it got a lot easier. Accidentally killed 1 person and then had to kill two guards because they got trapped on a stairwell and were blocking progress, and I didn't feel like reloading the save at that point. So mostly a stealth run.
What I mostly liked about Edo is that so many games absolutely flub stealth mechanics if they're trying to graft it onto something that doesn't really support it or have incredibly restrictive rules around getting caught
cough ZELDA
cough. I don't know if it was true with the SNES version but they did a really good job here. If you get caught you can almost always run away from the fight, there's no penalty from using your invisibility cloak, it's pretty easy to get around guards, etc. So it's one of the more forgiving stealth bits I've seen and it's just really run to play.
The only real complaint I have with it is that I feel like the final boss would be an absolute slog with 0 kills under your belt unless you picked up nearly every item and know where the safe spots to park Oboro are.
Next chapter for me is Far Future since that's the last chapter I played on the SNES version but never completed. Then Near Future and Prehistoric which I played in the SNES version to completion. I've intentionally saved these three chapters for last because I wanted to play the ones that were "new to me" first before replaying stuff I'd technically already seen. And I'm greatly excited to see Near Future in 2D-HD.
Another thing that was kinda surprising is the difficulty. The game doesn't tell you to grind, it also doesn't tell you that you're suddenly going to be fighting a boss alone without your party. I don't think that's fair... I also didn't save much so I had to redo a good chunk of the entire section, so annoying
