stage = 0 要增加蛇在游戏中的速度，你只需要调整`pygame.time.Clock().tick()`函数中的参数，以提高帧率。例如，找到以下代码片段：
clock = pygame.time.Clock()
# 这里调整游戏速度，例如：
clock.tick(10)
将 `clock.tick(10)` 中的参数 `10` 增大，例如 `15` 或 `20`，这样蛇的速度就会变快。请记住，数值越大，蛇移动得越快。通过这种方式，你可以调整游戏速度以适应你的需要。完成后的代码片段应该看起来像这样：
clock = pygame.time.Clock()
# 调整此值以改变游戏速度
clock.tick(20)
请将上述代码更新到你的游戏循环中，以调整蛇的速度。
