Great news, Jeff! I know how hard it is. It may not help much with publishers, but it improves your chances of getting an agent. Take screenshots and add them to your "press packet."
(and never neglect an opportunity to plug your tome)

Thanks. I have an agent who indicates that the Amazon rankings can make a difference as he shops the book. If there's already proven market appeal established (even without an advertising or marketing campaign or budget), it lowers their risk threshhold.
Anyhow, we'll see where it goes. I am going to write all five books in the series in any case.
