Well, this is...cryptic.
I think the main thing I want (other than "any idea what's going on") is a "click to continue" after scoring, so that I can look at the three cards, look at how they scored, and try to learn something, anything, about the system. As it is, I'm going, "Oh, cool, +12 for circle-circle-diamond, by playing a--god, was it two green cards? I think a 3?"
