It’s pretty straightforward and easy to follow, if you read the dialogues and pay attention to the surroundings that is.
I played it the first time without a walkthrough and it went all pretty smooth.
And the quest log is crystal clear almost always.
And of course sometimes you’ll find the occasional obtuse obstacles that maybe will make you scratch your head, but aside from a few of those the game is doable without it.
Then there are the choices that will impact the story and characters in different ways; sexually wise (like Romance route, Corruption route, NTR route) and gameplay and plot wise.
All of them (Except one regarding the story) are clear on their consequences and content, and the game doesn’t trick you into choosing options that seem good at first only to betray you later.
So have fun!
