That's just one error. You've removed the source, and I don't have time (or any reason) to mess about with your archives, so you need to look at
findTheCheese.saveScores(findTheCheese.java:415)
NullPointerException means you have an uninitialised variable being used on that line.

I tried removing all the codes in

saveScores()

instead put a JOption message

"Write anything"

but it wont output after the game ended.

Use more System.out.println(...) statements at key points in your code so you can see what is being executed and what the important variables' values are. I don't have your current code in front of me, so I can't say any more than that.
