It's a great game. However, it seems not supported anymore. I have made some updates to the game. Find version 2.1 here on sourceforge.

All in all I like this game. I did encounter a problem. I got down to having one card left to turn over and I noticed that there were four cards that I needed to finish the game, which means that three cards were missing. I took a screen shot of it because I wanted to make sure that I was seeing this right. I am using version 2.1

good job
