pygame，这是使用类的正确方式吗？

import pygame

class Game:
    def __init__(self):
        pygame.init()
        self.screen = pygame.display.set_mode((800, 600))
        self.clock = pygame.time.Clock()
        self.is_running = True

    def run(self):
        while self.is_running:
            self.handle_events()
            self.update()
            self.draw()
            self.clock.tick(60)

    def handle_events(self):
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                self.is_running = False

    def update(self):
        # 游戏逻辑更新

    def draw(self):
        # 图形绘制

game = Game()
game.run()
