I don't agree with this, but I think it may be partly a matter of taste. The main character is more of an introvert and we see everything through his... eyes. He can pay attention to many details because it is his character. I also think that more detailed descriptions help you better imagine things in this world. Even if these are simple things that most of us do not pay much attention to on a daily basis. Of course, stories with too detailed descriptions can be boring, but in my opinion the descriptions here are okay.
Maybe it's a matter of taste, I don't know. I've seen a few visual novels that were poorly written and for me the level here is decent. The action itself is a bit limited because everything is happening on a ship in a closed space and everything is only gradually starting to reveal itself. That's why the atmosphere here and the tension must be built slowly.
