Firstly, the game is good, so this is not an issue. You are indexed.
My first suggestion is to add a web version. Tons more people will play the web version, than the downloadable version. The only way people even download my game is a charity bundle.
Secondly, using reddit.com and other socials are helpful. The itch.io community can also help, but not as much. However, devlogs only do anything once you have followers. They are useless right now.
Lastly, it can take a while. You can't make it to "New and Popular" anymore, because the game is not new. You will have to aim for reaching the Popular list for the smaller tags.
Also, check that your sensitive/adult content is off to avoid the adult stuff on new and popular.
