The game can restart by clicking the yes option at the popup dialogue box. If no is selected, the game exits normally without
System.exit()
. Game threads terminate using a boolean variable andJFrames
are disposed at termination and between restarts.I understand that the replacement of int directions with the Enum could be done as a different pull request but I thought it would be simple enough to do it here. I will separate them if necessary.
