< 绿林卫士>>是作者在97年，临近大学毕业的时候开发的，当时国内盛行红警，游戏开发行业才刚刚开始。虽然本游戏在98年初参加ENIX全球大赛获优胜奖，但很多设计思想还不成熟。不过对于想入门入门开发游戏的程序爱好者来说这是个不错的参考。 本游戏利用了当时刚推出的DirectX 2D和DirectSound技术。 由于动画太大，程序略去了Avi文件，请启动程序后按ESc键进入菜单。 (<Greenwood defender>> is a writer in 97 years, when graduating from college near the development, when the prevalence of domestic红警, game development industry has just begun. Although the game early in the 98 to participate in the Global Competition by Enix prize, but many are not yet ripe for design ideas. But like the development of entry-entry procedures for the game lovers, this is a good reference. The game made use of then newly introduced technology DirectX 2D and DirectSound. As a result of too much animation, the program omits the Avi file, please start the process by the ESC key to enter the menu.)
