But my one more question is that how can I promote my game as all the peoples don't want to play Indie Games only youths and kids who know wants to play Indie Games.
Viewing post in My game is not appearing in the search too ^^
A lot of people want to play indie games. Many people even prefer them nowadays. But people are also busy, and they may not find your game exactly when they go looking for something new. Use devlogs, those help a lot. And use social media! Don't restrict your promotion work to Itch. Get a site of your own. Get a blog. Comment on other blogs. Post in other forums.
