Pros:
Overall the story is laid out with good intrigue, the pacing starts out slow but builds up really nicely presenting the mystery. It's a game with a lot of information to give you, rather educational for me so far. The cinematics presentation of the game is very strong, characters are likeable and relatable with their quirkiness, it's a game with a lot of thoughts put behind the story.
Cons:
My feedback is I wish the art can use more improvements, especially if this game is related to Visual novel genre where at most the gameplay is clicking choices, it's pretty important to have good visuals, if nothing else, I say improve on the backgrounds will help a lot, and a bit of tweaking in character anatomy on the lower half of the sprites and some of the CGs, bgs looks clearly like photos being rendered by filters, currently the dark edges of the background fights with the characters' lineart its rather distracting, line art in background arts need to be thinner than the characters themselves in order to fall back visually and not draw as much attention, it is consistent, but not pleasant to look at unfortunately. Since you did pick the anime style, it is important to keep to the look of the genre and not move away from it too much.
The text also does need a UI help too, the current version I played have no text box frame, the text fights with the background visually so it's straining to read.
For BG render update, maybe this plugin will help if you don't have a budget for the bg: https://fotosketcher.com/
Another quick way to fix the bg is turn all of the black lines in the BG arts brown for modern/historical places, blue color to replace sci-fi spaceship places, that would stop competing with the characters and you can run it with a simple brown/blue filter and it will still work quite well.
Hope this helps.
