Hello there.
Ok, so after some recommendations and research, I have decided the best next step for me is to work on lighting. As this is a "horror-themed" enviorment, lighting will be a necessary essential if I want to tickle the senses and convey as sense of darkness and depravity. Once I finish that and optomize the levels, I'll work on small refinements and then set my focus on the demo, which will include (at this present time) 3 levels. Also, screenshots will follow, including pics of the "monsters", which will become a much larger focus after the initial few levels.
