Day17 - 帮蛇多加了暂停与继续

class Game{
    startGame () {
        this.snake = new Snake();
        this.start = true;
        this.bgm.play();
    };
    pauseGame () {
        this.start = false;
        this.bgm.pause();
    };
    continuedGame () {
        this.start = true;
        this.bgm.play();
    };
}
