This doesn't have alot of proof it's more of an idea I had but anyways

More of this theory revolves around having the fear of being unable to change the past, and blaming yourself for it.

When we go into the real world parts what if that wasn't us. It was the memory of a child. Who are the other people in the game? Jade and Sam are there with kinito. They act like their forced to do this like kinito tells sam to say hi.

What if Jade and Sam are the trapped souls of two children.

Jade even warns you if you have a second monitor. Why would she do that for a stranger? Unless, these two kids were childhood friends take away back in the early 2000s. Then the fear of being unable to change the past leads the protagonist to blaming themselves for it. Kinito used this to their advantage, showing you your friends in your face then taking them away all again.

Kinito has even put a human heart and body bag in their houses. Sam then tells the player it's all their fault. What if Sam didn't actually say it, the player just imagines it due to their fears.

But thats just a theory.
