Hi Josh, I'll pick this up and check it out.
As far as getting some love, I'm not sure I'm in any position to tell you, since I've only been releasing papers for a month or two (and mainly for fun), and your other papers do very well and have sold far more than ours.
But I did notice our latest one (Mystical Skull) was on the top new paid on my tablet market, right on the front, in the top 10 (it's a new category, I guess like just in but less constantly moving?), which has helped our modest sales.
We do have a free version of it, and we make sure in the preferences to always have links to get more papers, and to rate it in the market, etc. It has all 5 star reviews so far so maybe that tickles Google's algorithms. I think the free / premium version thing works, as long as the free version doesn't just give away the whole cow, and doesn't annoy them. People seem to like to upgrade to support things they like. We do plan to do some experiments with not having a free version though and seeing how that compares.
If there's any of the bigger dogs on here that can chime in I'd love to hear more voices on this, too?
