And as a follow up to this post (https://itch.io/post/8918177), here's what the improved lighting system planned for the beta versions looks like in a double width hall with a single light source placed around the center of that hallway. If you look closely, you can actually see that the side of the wall that is closer to the light source's origin is brighter than the wall on the side that is opposite to it. Which is another improvement that this system has.
