This is off to a fantastic start, and I can't wait to see more.
This rating is based on the game as it currently exists (v0.01), not on potential, or downrating because it's early in development.
Renders are quite good. Not the best I've seen, but I've certainly seen worse.
The story (so far) is among the best I have read in this type of game.
Dialogue is natural and fluid.
If I had to find a flaw, I guess I would say the animations are not the best, but I am picking nits when I say this.
If you're the type to just click through a VN looking for the naughty bits, don't do it with this one, you'll be cheating yourself.
