I just recently finished this game, and just wanna say it is an incredible adventure. 4.5 is my rating as it wasn't perfect and the devs will agree themselves, but they took it as a challenge to improve, and the game gets better for it.
I would like to mention that at the start I was very doubtful of this game, as playing it recently it has not so great graphic in the start and there was way too much text/info dump to start the game, so I even uninstalled it to play other games first, but when I reinstalled it and played it when I had the time, I can say that it was great that I did, I loved it, graphics got better as it progressed, so do not let the first impression let you stop from experiencing this adventure.
It was the first game of the dev and it showed at the start, but good thing is that they worked on it and improved (it is evident clearly in their new game too) and by the end it is an overall brilliant experience. I also like to mention that the dev/storytellers treat side characters well, as even bad bullies or less popular side characters get amazing twists and that adds to the overall feel.
All relevant characters are good (nature wise or look wise, except the MC but that is by design/intent and it is used to provide some great moments), there is a very engaging story so you just doesn't slog through it to get to good bits, Humor is top notch. I would play this even as a non-adult game.
My thumbs up to everyone involved in creating this, thank you.
