It's a slog to get through the absolute abundance of details this VN throws at you. It's walls and walls of text of irrelevant things, like what coffee each person in the room ordered, their clothes, every single change of expression, every single thought the MC has on EVERYTHING... It's just too detailed. The author obviously wanted to write a book, not a VN.
Also all characters are incredibly flat. If someone has a habit of saying "dude" - he will say it every single time he is talking to someone. If someone is secretive - he will be secretive about absolutely anything and everything, in the most blatant way possible.
Fake choices aren't helping keep my interest either. What's the point of even giving choices when the player MUST go through all of them? Just play out the scenes one by one and don't waste my time!
And the few real choices don't feel like choices - the MC doesn't stand up to the challenge he just chose, he is just being a dead weight in every situation. It's not rewarding or interesting to be this person and his overwritten backstory is not making things better, it makes them worse.
The MC is NOT player incarnate, you are just with him for the ride and it's annoying as hell.
