I have noticed that on some screens the buttons are in a little bit different position and on others they aren't. I like the buttons being moved a little so that if someone double clicks it doesn't go past something.
The DW and I were playing and she has a tendency to somehow double click :( and that causes problems because you can't go back or undo something and you have no idea what you just missed. I would recommend that you move the buttons a little or allow for a limited undo or go back so that if you land on a square and it says you are going to need to do something and then click twice instead of once you will be able to figure out what you were or are supposed to have done. :lol:
Just a thought.
I really like the game and think you have done a great job in putting this together.
