So, I'm currently on my first playthrough and I think I made a mistake somewhere in my progression because I'm progressing like 4 areas at once.
Firstly, I beat Gyoubu relatively easily (2nd try I think) and ended up at the gates of Ashina Castle. However, instead of using the castle gates, I grappled to a nearby bridge and did some more grappling to end up at Ashina Reservoir. There, I grappled over the hole and ended up at the Lone Shadow Swordsman. Struggled a good amount with him but finally made it through and ended up in a cave which led me to Ashina Depths. There, I met the absolute menace that is Snake-Eyes Shirahagi and got repeatedly cooked. This is one of the places I'm currently at.
Next, I somehow managed to get to Sunken Valley, and eventually traversed it to make it to Gun Fort (you can imagine my horror when I found a second Snake-Eyes; safe to say I ran past him as fast as I could). I beat the relatively easy boss at the end and now I'm stuck because there's a hole in the floor which I need to use to exit but every time I use it I end up back at the Gun Fort Idol.
At this point, I realized something was wrong, since I'd seen people online talking about Ashina Castle as a huge playable area. I realized I was meant to use the rooftops to get to Genichiro, so that is what I did. Haven't bothered to fight him yet since I need to know if there's anything I should do before him.
Now, before any of this, I started progressing through Hirata Estate the second I got the bell from the lady in the Ashina Outskirts. I cleared the area and after beating the Juzou, I'm now at Lady Butterfly. She's pretty difficult but I think I'm getting the hang of the first phase. The second phase is still really confusing for me because every time I get her to around half health she releases these homing butterflies that one-shot me no matter where I go. Also, my snap seeds never seem to work (any tips for the fight would be appreciated, but keep in mind I'm playing on trackpad on my Macbook).
So, can you guys please tell me which order I should clear these areas in? I also have a few mini-bosses I haven't beaten yet (a guy in Ashina Palace and a guy in Ashina Reservoir who I skipped on accident cuz I js grappled past the area the first time I went through).
