shell游戏:扫雷

期待各位帮忙测试,如有BUG,请及时告知,谢谢
转载请保持版权声明完整,十分感谢

下载代码:
http://bitbull.cn/works/mine.sh

屏幕截图:
*

运行环境:
bash
80x24终端

usage:
$chmod 755 mine.sh
$./mine.sh

按1-3选择对应难度,4退出

方向:
上:w 下:s 左:a 右:d
标识地雷:
FLAG:f
挖:
DIG:j
重玩
NEWGAME:n
退出
EXIT:x

规则:
玩家可用方向键移动指针,按j挖雷,若挖到地雷,则游戏结束.否则,游戏将在你所挖方块内显示该方块周围8个方块内所有地雷数.若怀疑某方块为地雷,可按f键进行标识,以避免误挖.挖开地图内所有非雷方块则获胜.
