Hi, what you're describing happens to everyone. The problem is simple: we have too many games and not enough players.
If you want your game to attract players, you need to build a community and actively promote it, not just passively wait.
Additionally, your game is only targeting one platform, Android, and Itch isn't an Android store. So, a good portion of the people who might see your page aren't going to download the content because they're not interested in downloading casual android games from Itch.
We don't have player statistics or hardware specifications, but if you look at the 1,200,000 indexed games, only 90,000 have an Android version. This also indicates that it's not a store focused on Android.
Furthermore, no matter how accessible your games are, Google is constantly adding barriers to installing apps from outside the Google Play Store, so not just anyone can install your apps.
If you're only going to create games for Android, it's best to try to publish them on Google Play, but you'll have the same problem there; these days, you need to do active promotion.
