I think you should wait until this game done and some time later I don't know how much time you would perfer then think if it would be worth it to make, possible to make, and fun to make.
I've learned from my own visual novel I'm working on is that just writing stuff down and then looking at it later can help to see if you like what is written at least that helped me.
What I'm trying to say is I like your writing and enjoy It and I'm excited to see where it goes.
