编成一个俄罗斯方块游戏

非常感谢您的提问！以下是一个简单的俄罗斯方块游戏的代码示例：

import pygame
import random

# 游戏区域大小
WIDTH = 10
HEIGHT = 20
# 方块大小
BLOCK_SIZE = 30
# 游戏区域左上角坐标
OFFSET_X = 50
OFFSET_Y = 50
# 方块种类及其形状
BLOCKS = [
    [(0, 0), (1, 0), (0, 1), (1, 1)],  # 正方形
    [(0, 0), (1, 0), (2, 0), (3, 0)],  # 一字形
    [(0, 0), (1, 0), (2, 0), (2, 1)],  # L形
    [(0, 0), (1, 0), (2, 0), (2, -1)],  # 反L形
    [(0, 0), (1, 0), (1, 1), (2, 1)],  # Z形
    [(0, 1), (1, 1), (1, 0), (2, 0)],  # 反Z形
    [(0, 0), (1, 0), (2, 0), (1, 1)],  # T形
