Nights on places where there is no source of light are really dark, ok.
But even on forests without moon or inside a room without windows and lights, we will be in a pitch black ONLY if the lights turn off suddenly.
And even on a suddenly change of light to no-light, with time our eyes will ajusting.
KCD already have something like that during the day when we enter on a dark place or come out from that dark place to outside. Henry’s eye in seconds ajust with that change.
Henry’s eye doesnt do that at night. His eyes works always as on a high noon on his face walking in a no-light room.
Human eye ajust itself with time on a dark place.
If we at night, with lights on, close all windows, doors or anything which throw light into our room.
Turn off all lights and light sources. You will be in a pitch black room, but keeping the eyes openned and wait, with time, our eyes will ajusting (our pupils expand and contract to allow more or less light pass through - as a camera’s lens do).
I’m not talking about a suddenly change of light to darkness, but a gradual change which our eye will ajust slow to that.
I don’t know if is possible to add this gradually effect which Henry’s eyes will ajusting with a short time, but if not something could changes to allow player to see something besides only black.
Our eye getting used to darkness is far way from something like night-vision, which we can see dark places very clearly.
