I absolutely love your writing and would be very sorry, if you stopped doing games.
There's a link I came across a whileback about maketing on Kickstarter that could help you a bit

Social media is really important, but tagging is even more so.
If you start a twitter, vnlink and some others tags like wipwednesday or screenshotsaturday might be useful. Or ren'py for the engine.
Or just visulanovel and otome tags.
And I find pictures draw my eye easier than just text. Just a thought.
Some devs make a tumblr to post updates or answer questions, like what are the favourite ice cream flavours of the romances options or lore tidbits.
I know that always keeps my interest alive when the game development takes a while and there no current updates.
Also, tumble searches use only the first five tags I've hear, soemthing to keep in mind.
Good luck.
Ps I hope that doesn't all sound rude, I'm not trying to be. I'd really like you to share your games with a lot more people and those are things I've noticed about my own browsing.
If anything's not clear, I have an awful cold and am not my best currently.
