这段代码中的错误是因为`flag`和`shengmingzhi`变量没有定义，需要在代码中添加它们的定义。另外，`endgame()`函数也没有给出，需要根据需要自行实现。修改后的代码如下：

bool flag = false;
int shengmingzhi = 3;

void Game::key_thread(void* arg) {
    putimage(zuoqishi + mouse.y * size, shangqishi + mouse.x * size, &bgs[2]);
}

void Game::timer_thread(void* arg) {
    bool flag1 = false;
    while (seconds >= 0) {
        int gewei, shiwei;
        gewei = seconds % 10;
        shiwei = seconds / 10;
        putimage(1012, 600, &number[shiwei]);
        putimage(1062, 600, &number[gewei]);
        Sleep(1000);
        seconds--;
        if (flag == true) {
            flag1 = true;
            break;//说明时间内走到了终点
        }
        if (shengmingzhi == 0) {
            break;
        }
    }
    if (seconds < 0) {
        flag = false;
        biaoji.time = true;
    }
    if (flag1 == false) {
        endgame();//根据需要实现
    }
}

void Game::game() {
    _beginthread(key_thread, 0, NULL);
    _beginthread(timer_thread, 0, NULL);
    Sleep(10000000000000000000);
}

注意，`Sleep(10000000000000000000);`这行代码是无效的，需要根据实际情况修改。
