I'd rather not do marketing for my game for several reasons. The most important thing is that I use Illusion assets to create the art and this alone justifies an option in being an unknown dev.
In addition, I like to make the game for myself, and when the game gets known and starts to generate expectations, the development process gets annoying and the author has to stay policing the whole time thinking: "will the players go like this? "
Incidentally, this concern ruined my enjoyment in doing the HS Tutor initially, instead of making a game that I found amusing, I tried to be guided by what the players say is fun and the result is a relatively boring game (for my tastes_. Incidentally one of my biggest goals at the moment, besides finishing all the main storylines of Solvalley in 2018, is to transform HS Tutor in a game that I like.
All these things, in my opinion, justify me to continue in the shadows without making much money, without doing marketing, etc. What I get at Patreon is enough for me to survive, after all.
