First, thanks for sharing your work with us.
It's not the time to do a review yet, I don't believe it's fair to analyze everything that is yet to be developed.
There are many good points in this game.
The fact of breaking some paradigms with a black MC which is quite unusual.
Although you haven't modified some of the base characters available in DAZ already pre-made, there is a very good job here with the lighting and the use of the characters' expressions.
Scene fill is quite satisfying.
The sets are not so original, and seem to have no contrast with the scene to the point that I think the college looked more like a police station than a school. (I think a lot due to the characters and the way they look and dress)
Another point is that there are gaps when the presentation of the characters in the prologue, it is very vague to understand who the characters are and what their relationship with the MC is.
I love games where the dev has a special job with the GUI, it shows that you care about the unique experience of the game.
Hugs, good luck with everything, I'll be following.
