How do I install this game?

I decided I would try Super Mario Run due to it being highly anticipated and positively reviewed. I searched for it in the Google Play store and it did not appear. It didn't appear on Nintendo's "all apps" page, and all links to it on the internet gave me an "Item not found" error. So, I downloaded it from APKMirror. When I try to open it, it just sits there with a black screen (absolutely nothing happens). >150 MB is too large for an app that does nothing.

So how do I install the game?

Where did you find the apkmirror? I would like to have a try.

For me, it requires an update, but I can't get the update on Google Play.
