As sad as it can be sometimes, the game development industry is so heavily saturated it can be difficult to get noticed.
There are hundreds of projects on itch.io that are very similiar in style and gameplay. It does not matter if you've put hundreds of hours into making a game if dozens of other people have also spent hundreds of hours to make games that are similiar to yours.
As a developer, your projects alone will not set you apart from the crowd. You need to be able to connect to your audience on an emotional level.
For example, Johan Gronvall the developer of Bopl Battle creates YouTube Shorts to talk about his game. He's even taken recommendations from his audience and implemented them in the game. When he finally released Bopl Battle, the people that followed his YouTube Channel were super hyped and purchased the game (some even did Let's Play videos).
You can’t just post a game and expect the money to roll in. You need to convince your audience that the game is worth their time, attention, and money, ideally before they even land on your project page. How you do that is up to you.
