你可以在 `while(1)` 循环中加入一个计时器，每一秒钟减少一次剩余时间，并在屏幕上显示。当剩余时间为0时，跳出循环并执行 `endgame()` 函数。

修改后的代码如下：

void game() {
    int seconds = 60; // 设置游戏时间为60秒
    while(1) {
        cleardevice();
        update();
        putimage(zuoqishi + mouse.y * size, shangqishi + mouse.x * size, &bgs[2]);
        char key = _getch();
        switch (key) {
            case 72:
            case 'W':
            case 'w':
                if (mouse.x - 1 >= 0 && mapp[mouse.x - 1][mouse.y] != 0 && mapp[mouse.x - 1][mouse.y] != 2) {
                    mouse.x--;
                } else if (mapp[mouse.x - 1][mouse.y] == 2) {
                    // do something
                }
                break; //上
            case 80:
            case 'S':
            case 's':
                if (mouse.x + 1 < ck && mapp[mouse.x + 1][mouse.y] != 0) {
                    mouse.x++;
                }
                break; //下
            case 75:
            case 'A':
            case 'a':
                if (mouse.y - 1 >= 0 && mapp[mouse.x][mouse.y - 1] != 0) {
                    mouse.y--;
                }
                break; //左
            case 77:
            case 'D':
            case 'd':
                if (mouse.y + 1 < ck && mapp[mouse.x][mouse.y + 1] != 0) {
                    mouse.y++;
                }
                break; //右
        }
        Sleep(1000); // 等待一秒钟
        seconds--; // 剩余时间减一秒
        cout << "剩余时间：" << seconds << " 秒" << endl;
        if (seconds == 0) { // 时间到了，跳出循环
            break;
        }
    }
    endgame();
