title: Link to paid version in Google Play -- how?
body: <p>I am making a game with separate free and paid versions. (I'm using CocoonJS to convert from the source Javascript to an APK)</p>
  
  <p>I want to create a link from the free version to allow the user to purchase the full game. I want the user's Google Play app store to open to the paid version screen. How can I do this?</p>
