Hey. I feel you.
Your situation resonates with me. I want my game to soar to new heights and reach popularity when it fully releases, but I'm still very new to everything and I don't know how to get attention from users on itch. It's really hard... You have to put lots of effort into getting your work noticed around here...
But that's just par for the course, right?
The thing about monster tamer games is that they are immediately seen as Pokémon clones, even though most of them are MUCH more than that (look up "Cassette Beasts"). Just like how indie RPGs nowadays are immediately compared to Undertale, for instance. It's up to the creator to come up with a way that can make their project stand out, and that's really hard...
If you asked me, I'd say that your work is quite good! The pixel art is expressive and shows personality, the designs are charming, and you do seem passionate about what you do (the most important part).
I don't have an issue with this, but your main problem could be how close to Pokémon your assets look. I've seen this happen before; If your work looks too much like a successful and renowned title, people will write it off 90% of the time. This combined with low interest in monster-taming games, could be the popularity issue.
Anyway. I'm gonna look at some of your work now, it looks cool!
