i was interested in taking the test, but i had a question i hope could get answered. is there any physical danger, or sudden surprises?
There is no fail state in the software (you cannot be 'Game Over') nor are there opposing forces against the patient. Think of it as a walking simulator. Note, however, that two of the different possible endings demand the patient to simulate some form of harm, but none of those situations linger nor makes a spectacle of it.
Every new diorama is introduced by a sudden change in lighting and the sound of a projector being turned on, which might constitute a surprise for certain patients, depending on how they approach the interactive zones (although the zones are clearly indicated by floating lights).
It is a difficult question to answer, since it relies on a lot of personal preferences, but we assume it is a safe experience. Do not forget that the ESC button brings the software to an immediate stop (no sub-menu or confirmation needed), instated as a fail-safe in case of anxiety.
