Visually stunning with a very interesting story, though the dialogue is sometimes a bit off. Is it translated from another language? That's how it feels anyway. It might be a good idea to have a native English speaker proofread the script.
Another thing that I noticed is that it's kind of unclear what your relationship to all of the people are. How long they've known each other, how close they are before the game starts, etc. Nikita for example seems to switch between having known MC for months and as if he just started working with her a week ago in the way she talks to him.
I'm very much looking forward to the next update, though.
