I can't tell if it's a bug or I'm just confused, but after I go into the vent, the whole screen just goes black. I can still hear the moving sound effects, but I can't see anything or get the screen not black again.
It should not be. You must be transported to the next room and the screen turns on again. Can you tell which room it was in? Have you tried switching cameras on a black screen?
I understood where it is. It's in the first room. This is a bug that I will fix. Although it seemed to me that I turned off the ventilation in this room.
