Is the game too bad to download?

Well, I am an indie game developer. And as time goes on, I am improving in making games. But, what can I do to promote my games? I am not able to find my own game by searching it on google play with full name. Kind of lost here.

You can only find the game by searching com.onethumbgames.tankcombat. Is this game too bad? Can anyone lead me a way how I can word out about the game? Really frustrated
