Excellent overall, despite a notable bug
A very good adaptation of an awesome card game. The AI plays very well. My main concern is that the "continue game" option often fails (unreadable saved game). I suggest the developper to use two save files, and write alternatively to one and the other. That way, in case the last save state is unreadable, a failsafe to the previous state could be proposed to the user.
