Games can be downloaded without visiting a page either through the app, or if someone owns the game and they go directly to the download page from their library.
Viewing post in Analytics Question - downloads/views
Thanks Leaf! I had suspected as much, so it's great to have that confirmed.
It would be great some day to have more visibility into update downloads vs. new user downloads as well as some more data on where users came from. The data on the dashboard and what's available in Google Analytics can be a little lacking here, making it hard to properly attribute where a download came from. Not the end of the world though.
Love the site, great work!
