I guess that's just one of the disadvantages with a big site like itch.io, your works can drown in all the other content out there. I had the same experience when I signed up for the GMTK game jam, I made a game I'm proud of, and I felt it didn't get the attention it deserved because there were just so many thousands of other (really good) games out there.
I guess just keep trucking and making stuff, eventually you'll probably make a name for yourself. Also it helps to promote yourself in various (non-intrusive) ways. I really like your style, by the way. If it fit the mood of the game I was making I'd gladly use your assets.
