It is difficult for me to rate the game.
It definitely has potential for 5 stars, but at the current state I'd give it 2 or 3.
The art is amazing. Some of the best art I've seen in these games, if not the best art. I recognize that it's a particular style, and perhaps not everyone's taste, but I personally love it, and the attention to detail is magnificent.
The Prologue and Chapters are a bit misleading, since Chapter 1-3 are actually also prologues. The game itself, with actual options, starts at Chapter 4.
It takes a while to get to Chapter 4, and while I can see how the developers might want to use C1-C3 for buildup, it could probably be done quicker and less tedious.
The quests aren't bad, but they are confusing. Oftentimes you find yourself completely baffled and without any clue what to do. Sadly, the help function does not seem to be implemented correctly for Chapter 4 and onwards.
The game does become very grindy. You have to do a lot of the same things, wait many days to see a possible outcome, and sometimes there's just no outcome because you didn't "do the right thing" to progress. Back to grinding and waiting.
The game reminds me of the oldschool Adventure games, where you have to guess, guess, guess some more and maybe find a solution or simply give up.
The story and amount of text isn't bad, it's actually rather average. The game does, however, force you to watch the same "scenes" and dialogue again and again, and there's some very slow animations you can't skip.
As I said, I don't mind that the game is slow, but during Chapter 4, and especially in Chapter 5, the game doesn't just have slow progression, but also becomes fairly grindy.
What I would love to see more of in the game, would be more things to do during the week, and not having to wait for a certain day and hope that you did the right thing during the week to progress. I would also like to see more "rewards" along the path, to keep the player interested.
The sex-scene at the end of the Prologue is very well done, but after that it will take hours upon hours to see any more of that kind.
