I think you need to smooth out the edges of this project. Make the demo of this game a little better, fix the mistakes, and then write a couple chapters of the story. After that, publish a new demo.
Regarding the story. I would advise you to write a backstory of the characters, at least the backstory of the MC at the beginning. Where he's from, who he is, where he's going, etc. At least briefly. Because right now it looks like two strangers met and went somewhere for unknown reasons, -Why? - Just because...
Let's say the protagonist can share his live story with Fox as they walk down the road. The fox might say something brief about himself in return.
From my point of view it is important that at least something about the main character is known at the beginning of the game, otherwise it feels like a gap.
You can write this VN, you did well for a start, don't give up)
