The music is nice, the character design and portraits as well as the animations elevate the experience a lot, my favorite part were definitely the endings, such a good closing for the story, very satisfying.
Another great aspect that was really REALLY well done was all the choices we make trough the game, even if they don't affect the ending they go a long way on making the player actually relate and feel the story and emotions of the character.
I personally related a lot to Mari(gold) and her views on life so I often clashed with the narrative of the game but that's more of a personal opinion than anything and it did not affect my enjoyment of the game at all.
My only "issue" is that maybe the story stretches a bit too long in some points, although is very nice to see the slow decent to madness of the protagonist and how everything slowly crumbles, regardless of who's fault it is; aside from a really nice spooky story it makes for a great self introspective cautionary tale.
Keep up the good work!
