MiniLegend: What the Hell?

I'm trying to play an IOS RPG/Card game that is so new, it seems to have no reviews yet (as of Oct 14, 2104). Well, here's a short comment:

I opened the game and went to the register screen. I carefully typed in my desired account name, my long password (twice) and my email address. Then I tapped "Register". I got an error message:
Account or Email not found.
Well, why should they be found? I haven't registered yet!
I tried again, very carefully (which means I had to retype everything), and I got the same error message.
The developer's website is http://www.pocketriver.com.

What the hell?

What the hell??

What the hell???

Don't Tailgate!

Here's wonderful technology: Don't you wish you could call a nearby driver's cellphone by dialing their license plate number? (I'm just talking about you and me; we wouldn't want anyone else to have this capability.)
