I really like this card game, but can’t find the app I used to use to play I so I thought I’d give this a try. It needs two changes and it can be a 4 star. 1. The cards are not easy to read, making it difficult to play. 2. It needs an undo button. Also, there should probably be a place to click on the game screen to get at the rules, for people who haven’t played it before. I’ll check on it again in a month and see if it’s improved, and if so, I’ll change my rating.
