“宇宙比任何人所能想像的大得多，如果只有我们，那不是太浪费空间了吗？”
忘了到底是从哪搞来的，可能是隔壁班借的，也可能是亲戚朋友给买的。
总之，打着手电筒躲在被窝里看到12点，还越怕越想看~
百慕大三角、UFO、消失多年的飞机、解剖外星人、水晶头盖骨、大脚怪、麦田怪圈、埃及金字塔……
今天的文章就是大家感兴趣的外星人话题！小编脑容量有限倒是想象不出来外星人长什么样子。
但是我可以卡通化一下这款外星人小游戏给大家！绝对不恐怖，甚至还有点儿可爱~
正文写游戏嘛？还是大家熟悉的pygame模块，主要是分为三块py源码文件。
游戏规则：我方控制炮台击落外星人入侵地球，每次可以重生三次，击毁一次外星人相应加分，进入下一关，完成全部关卡即可通关。
首先定义我方炮台类：有相应注释可看。
