Is that multiplayer matching? nice. But the signing up for an account is a bit much for a simple game.
I like the graphics of the cards, etc, but it feels to me like the wrong interface choice for rock, paper scissors. I was expecting to see animations of two people doing the hand gestures.
The six cards was a bit confusing at first, playing one game at a time might be better?
When you play this with a human, there's an element of skill, in that you look in the eyes of the other person and predict what they'll pick, based on what they choose last time. It would be good to mimic that somehow.
