Very cool visual style! I liked the shader you used; it adds a layer of corrosion and griminess to everything, which is very fitting for this kind of environment.
Unfortunately, I had a bug that, for some reason, prevented me from using the mouse in the game. So I was unable to look around or aim at anything and was walking backwards and sideways. I only got to the map crossroad and then decided to stop playing, because this was probably not the intended experience.
