I have already posted such message to Developers
forum, but I am not sure where it should be. So, just in
case, I put it also here.
Let me propose little improvements related to game
saving. Now, if I call Save Game file dialog and then
press Cancel, message Save game failed appears. I
think this is not good I just REFUSED to save game;
this is not fail. It would be better to output no
message in this case. If you are agree, here are little
changes in files Game.java and GameScreen.java.
