贪吃蛇150行的版本里重新开始游戏时速度未重置

[callmetaytay]

 if game_over:
                        start = True
                        game_over = False
                        b = True
                        snake = init_snake()
                        food = create_food(snake)
                        food_style = get_food_style()
                        pos = (1, 0)
                        # 得分
                        score = 0
                        # 重新设置速度为初始值
                        speed=orispeed
                        last_move_time = time.time()

可修改为这样，以修复这个bug
