'' Desc: A racing wire game! 2 players    ''
''       have to race across a wire       ''
''       without touching it at all. if a ''
''       player touchs the wire at all,   ''
''       they have to restart from the    ''
''       start of the wire. also, there   ''
''       is a fairStart mechanic where    ''
''       the players are forced to start  ''
''       at the exact same time to        ''
''       prevent cheating. Have fun!      ''
