Ask HN: What are we doing wrong with our first paid mobile game?

We just released our first paid mobile game "Anna & Fumbles" on Google Play.

But the game is yet to get any visibility or sales. What are we doing wrong? How can we rectify?

Anna & Fumbles is available only in USA, UK, Canada, Germany, Netherlands, Australia, and Bangladesh.
