There is a minor bug in the CCJ library that messes up when drawing messages
if they are the last lines of the program. To correct this, you can add
a System.out.println(""); instruction to the end of your
program to force the drawings. (It may be a "hack", but it works for now!)
No. You can just report the final scores. However, if you think that you know the trick for appending the scores to a message, you can attempt this as if it were in the "For the Ambitious" section. (Thus, this code will not be required, but it can improve your grade if you get it to work.) It is really not that hard... there is just a trick to it that you have to figure out.
