Sometime in the near future I'll release my first Android game. It's not going to be anything special, but I'm trying to make it as polished as possible and I would like to know what I can do to prevent it from falling into obscurity.
If you look hard enough, you can find some pretty well-crafted games on the Play Store that, nonetheless, are virtually unknown. I recently came across one developer that has published six well made games that are pretty fun and have good art as well; out of these six, two are moderately popular (10,000–50,000 downloads), while the rest have very few downloads (1,000 or fewer).
What are some techniques to increase your game's visibility on Google Play upon its launch?
