Android Code or Bust

As a rookie developer I find nothing more frustrating than useless comments on Google Play. Recently I got one that says "This Sucks, this app sucks bad" If it's not a good experience feel free to let me know why. I mean I'd prefer you not write a book, but emailing long suggestions would be fine too. It's not like I have 30 people working with me to make things happen, it's only one person. So Google Play, why can only the elitist developers reply to comments on Google Play? Are we not good enough for it yet? What gives, commenting started in July for some, it is November. That trial is long enough, let us in too so we can advance our business and customer relations!!!!
