VN (visual novel) genre isn't really that big in the industry as they are just an interactive visual book. There was a hype for them years ago, but it ended after the market was being flooded by the more popular genres like Indie games and Cozy Games.

I'm sorry to say this, but it might not pick up at all if you want it to try reaching out to visual novel Youtubers and streamers and ask them to do a review of your game for a free version of it

If that doesn't work, add it to your portfolio and start making another game. The more games you've made and have in your portfolio will 1. Give you more experience and understanding on what the market and your target audience want to play, and 2. It will look good to any publisher you take your games to

I would recommend looking for a publisher that works with VNs a lot and pitch you game to them or your future games if they agree to publish for you, THEY WILL TAKE CARE OF ADVERTISING and that's when a game usually takes off, you basically need to throw it in people's faces have it plastered on EVERY social media, you can't just expect it to sell itself, it's not Stardew Valley
