I checked the game. The Chinese meaning you said is cancel because of my negligence. In addition, according to your description, the elevator cannot be used because B2 is not enabled in the card authority. There is a puzzle on the computer in the upper left room of B1 East District - archives office. So you can go to B2, but it will be over soon. If you still want to experience it, you can try it.

OH! That's ok. I just want to know what's going on but that makes sense. Is it in a room that's not in spacetime? I can't wait to see it through. Thank you for clarifying the confusion. ♥
Update: I finish the ending and theirs a error pop up and a long loading screen appear but other than that the game was very intriguing. I love it.
Thank you for playing all the contents of the demo, because I am busy finishing the full version, so I have no time to deal with the demo. Fortunately, your experience is complete, although I don't know what caused the last bug. Normal ends at B2, and the investigation computer can enter a simulated battle field. In addition, according to the feedback of the demo, the English version of the demo is machine translation, which seems difficult to understand. I'm considering whether to still add English to the official version and promote it to English speaking areas?
