I can relate to that feeling of being underrecognized. It sucks when something you put genuine love and passion into seems to underperform. I myself have been following the development of your game for quite some time (haven't had time to play it, sadly), and you've put a lot of hard work into it, and the art style and character designs especially shine.
I think the best thing to do is to reflect on what you enjoyed about making it. Maybe bend into what you liked about making it into your future projects?
Either way, I'm sure that, even if it's not immediate, you and others get the support they deserve. Good art will always find an audience eventually.

For now I can't support artists by buying games on steam or donating on itch. I truly wish your game and other indie authors received more attention and support
