21 views and 1 download?
I have 958 views and 127 downloads and consider my succes pretty bad, now i changed my mind.
My recommendation (if anyone cares) to make Assets for itch.io prior making the game.
This will gives you some experience in game page making and draws some views.
My experience is that the Game Assets section gets far less traffic than the Games section.
Making some stuff for practice before starting your big heartbreaker project is good advice, assuming you don't already have experience working with the tools you plan to use. But unless the stuff you're making is really good and becomes really famous on the site, I doubt it is going to translate into success for your game.
(Also, I'd just like to point out that all you have made so far is some AI-generated graphics assets.)
My point here is that you haven't even tried your advice yourself.
11.9k downloads and 443 downloads, for the record. (Both of my games are playable in the browser, so most people don't bother downloading.) The one asset I ever made got only 65 views and 11 downloads during the entire time it was online.
I do not see a super-popular game on your account. In fact, I do not see any games on your account. So, no, you have not tried your advice yourself. That's just a fact.
My experience, as someone who has published both games and game assets, does not indicate that game assets are a reliable way of building a fanbase. Period.
Also, I don't really think 12k views are "impressive". I'm happy about those views but I am just making something I am passionate about and apparently have found a niche that isn't completely overrun. If my goal was to go commercial, those view counts would be absolutely worthless.
I delisted my asset a while back in protest about itch.io policy changes.
I mean, you said yourself that you have 1k views in total, so if you do have a game on your account, my response is no longer "you didn't even try your own advice" but instead "you tried your own advice and it was an abject failure". Like, if you're sitting at less than 1k, you are not in any position to give other people advice on how to become popular. Neither am I, honestly.
Also, I'm not a guy.
