I like the concept of the game, and it's a good time killer.
But I had some issues when starting out. Mainly being that the Jack card was said to be a wild card, but I could find no use or how to properly use it as a wild card. And at first I didn't know that the bad meter could decrease with each successful pair so it felt like I was very out of control for the first few rounds.
Adding more clarity on the mechanics and a difficulty setting for card speed or card columns would be nice.
