Absolutely not... You cannot blame this on anyone other than the developer for failing to include in-game methods of finding your way around, knowing what to interact with, and having a sense of where to go.
This is an RPGM game, but it is a 100% linear experience. So when you are playing a linear game, there should NEVER be a time where the player has no idea how to proceed and has to essentially bump into walls hoping something triggers. There's a difference between a player not doing their due diligence, and the the developer failing to make the game intuitive.
I'm sorry if you don't know the difference.. but when you see countless people having similar issues, it's not on the gamer, it's on the dev.
Also, the sex CG's are nothing to write home about. I liked the game.. but the further you go into it, the more it falls apart. This is case of a dev losing steam as the game was being made. I've seen this THOUSANDS and THOUSANDS of times... Where a dev comes into a project all ripped mg and raring to go, only to look steam and start cutting corners and cheapening out on the experience...
And this is a great example of that. The first half of the game is a 10/10... The 2nd half is a 1/10 because the translation goes to shit, the mission structure goes to shit, the quest log becomes mostly worthless... And quests themselves stop flowing into one another and stop flowing into the overarching narrative... And the main quest becomes a bunch of disconnected side quests.
But I'm not playing for the CG's... I just want play a good and well made game, and this falls a bit short.
