This VN is very uneven. Notably, some parts have really beautiful writing, while others are full of faults (I guess some parts were edited and others couldn’t?). There are also great imagery and beautiful drawings, but most of the VN only takes place in a vague blue background. The main characters have some interesting conversations, but others don’t quite make sense (on the music one, the characters kind of seem to switch places) or are cut altogether (I definitely would have wanted to read the beginning of their call).
The characters talk a bit about folklore without going far. The game page mention this VN being inspired by basque stories, but I don’t know what at all, so I can’t really comment.
Overall, there is a lot to like, but most notably the writing takes a deep dive in quality at some points, which makes it difficult to really enjoy. Still, good job!
