How to achieve Stylized Lighting

Hi there. I recently played a pretty cookie cutter horror game called “Eyeless Jack” with a friend. I thought the stylistic choices were actually quite unique and wanted to implement something similar in my game.

Here you can see some examples I took:

looking closely, you can see the lighting for this game is pretty fancy. Shadows stop abruptly and it resembles something close to Buckshot Roulette, or a toon shader.

How was this achieved aside from clever texturing if that’s not all it is? I’ve seen this done a couple times but I haven’t found how to do it myself.
