Without trying to sound too harsh, and apologies to the developer it does, this seems to be a case of "Launch mediocre game with no marketing to Google Play and make no money." I'm not really sure what he was expecting.

I suggest:

1. Use this as a learning experience for how the Google Play store works.

2. Find an artist to work with (this looks like programmer art).

3. Develop a game that innovates on the genre you wish to work in.

4. Try again, and keep trying.
