2. create and implement game elements, systems, and play mechanics using industry-standard tools, techniques, and production methods, including both art and scripting/programming applications. 

In this video I do all the art except for anything related to the Horror engine such as torch, doors, Levers, I also restriped the horror engine elements such as levers that affect each other or cause monster drop and even the door falling off becoming useless, I scripted the floor drop and candle element. I had designed the level but and did not do the enemy scripting.
