According to the test, after opening the elevator, you must download the original installation program in official website to enter the left room. Other versions are not available (address:/Judas-Mystery:-The-Stanwick-Legacy-Game-Info-5375).

If you download the free version and play it for about half an hour, a prompt will pop up for you to buy it, saying that your demo time is up, and the cost is about 60 RMB.
