The art in this game is absolutely it's strongest asset -- the game is beautiful! I loved all the small expression changes and details that went into all of the character profiles and backgrounds.
I liked that this wasn't straight VN, but had gameplay elements woven within the story, since that makes it much more engaging, rather than just being a lot of text on the screen.
This definitely gives me FF tactics vibes (minus the difference in battle system, of course), and I like the choice element that you've given the player with the skills / AP.
Overall, very nice game and I think with the changes you already plan to make, based on your comments below, it will only improve from here!
