使用DeepSeek生成基于HTML5的贪吃蛇游戏，效果非常棒，界面简约，操作简便。
提示词
帮我生成一个贪吃蛇游戏 基于HTML5
游戏说明
1 游戏控制：
使用键盘方向键（↑ ↓ ← →）控制蛇的移动方向
点击"开始游戏"按钮开始新游戏
点击"暂停"按钮暂停/继续游戏
2 游戏规则：
控制蛇吃掉红色食物来增长身体和增加分数
撞到墙壁或自己的身体会导致游戏结束
蛇不能直接反向移动（例如不能从左直接转向右）
3 自定义修改：
可以修改gridSize变量来改变网格大小
可以修改setInterval(game, 100)中的100来调整游戏速度（数字越小速度越快）
可以修改颜色、画布大小等样式
将这段代码复制到一个HTML文件中，用浏览器打开即可开始游戏。
