This game completely loses the point of pixel art. Even in a HD 2D sense, this is just a couple of pixel art characters that use WAY too many colours in a weird pixel-3D mesh environment.
The only game that has done HD 2D well so far is Octopath Traveler. The reason that game looks as good as it does is because it doesn't skimp on the art style consistency. It breaks the rules in a tasteful way with realistic lighting. Live A Live on the other hand is a mess of inconsistent pixels with poor lighting effects and a lazy half pixel half 3D environment.
The music is pretty good for the most part and the stories are interesting enough, but the art style is horrible and distracts from what made this game good in the first place.
Edit: Someone decided to reply to my review, so to further explain:
The art is inconsistent within itself, not the just the whole game, but every chapter. 3D and pixel art cannot be consistent. If you're struggling to understand why this is the case, look at the opening scene of the present chapter. The ONLY pixel art is the main character, everything else is 3D assets (which don't even look good to begin with) that are inconsistent with the pixel art. That cannot be considered pixel art and should not be advertised as such. If the dev's wanted to make a 3D game, they should've just done that.
Pixel art is an expression of simplicity and constraint. Using too many colours looks messy and unprofessional. The hair itself should only be 4 colours max (give or take) on their size, but I was able to count upwards of 10 different colours just for shading, and that's just the hair. That is entirely too many colours.
I compared the game's style to Octopath Traveler as it was advertised as HD 2D, the same advertising as Octopath. Not to mention the same company made this game (though I'm not sure if it was the same team).
