实现思路

按上下左右移动方块。

用一个数据矩阵代表方块的内容。

移动是整体的移动，而不是只移动某一些滑块，所以难度更大（主要是编代码方便一点狗头保命）

移动后会有新的数字生成，弥补原来没有数字的空格。

接收玩家操作

pressed_keys = pygame.key.get_pressed()
if pressed_keys[K_w] or pressed_keys[K_UP]:
map.moveUp()
elif pressed_keys[K_s] or pressed_keys[K_DOWN]:
map.moveDown()
elif pressed_keys[K_a] or pressed_keys[K_LEFT]:
map.moveLeft()
elif pressed_keys[K_d] or pressed_keys[K_RIGHT]:
map.moveRight()
