Music: Very atmospheric. I can't do it justice much by just saying it but you should give it a good listen.
Gameplay: very classic RPG with a twist involving emotions that, for how simple and interactive it is, feels like it hasn't been done before and can keep the player engaged. Some RPG elements are very intense and some are very quirky and simple that remind me of the likes of Earthbound.
Story: When it warns you about themes of depression, anxiety and suicide at the beginning it's no joke if you are sensitive to these types of thoughts. The game does a wondaful job weaving in the circumstances into all types of people dealing with this sort of thing; and how other characters around them deal with it as well.
Overall: I don't regret buying this game and I think it's something I probably needed in my life to some degree. From the sake of playing another classic-like RPG with good story and character development to showcasing some themes that not only can get dark but are also more common amongst people than we realize. I'd definitely give it a go if all these things are for you.
