Default [GAME][2.2+] Donkey Dodge

I have created a game called Donkey Dodge and uploaded to the Google Play Store. The app does not have any ads nor is it device intrusive. I merely wanted something uploaded to get my feet wet so to speak. My aim is to start placing for sale apps. The game Donkey Dodge that I uploaded, I expected more downloads than a handful. Is there something I can do to increase downloads of apps I upload?

I appreciate all the advice that I can get.

Many thanks,
