Played a bit today. It looks like a long demo so I will keep playing it tomorrow.
The art is fantastic. There is something about the banner art that I love. It is striking in a lot of sense. The writing has been enjoyable and easy going, the post-battle vs Rika is a fun read, though I don't agree with "Lyra effortlessly beat Rika" part. She gave me multiple beatings until I understood better what parry was.
The skill menu UI is a bit confusing. There is no clear indication you have to press Z again to select the specific skill school to upgrade, the only change are the costs appearing on the screen. Something more indicative should be used. In that note, it is not clear which skill is selected in the skill tree. A frame around it would be nice.
I don't have much time left today to play, sorry. I will continue my playthrough during the week and expand the comment.
