Unfortunately, and I hope this is not your experience, the way I understand the state of affairs in gaming in general is that if it's not as gorgeous as Mass Effect or as addictive as Candy Crush you're not likely to see many people caring.
Really, though, good on you for releasing a game! If making games is what you love, keep going; I just hope the monetization you're doing is more experimental than an attempt at making a living. People are cheap, cheap bastards, and your prices aren't even attempting to hit the whales that support most (if not all) profitable F2P games.
Edit: Also, please note that as many of us found out the hard way, Google Play does indeed show your freaking address as part of your listing, so you may want to remove it from the relevant part of your profile. It's not required but it's also not made clear that it'll be shown publicly if you enter it.
