Demo Update

Things that were updated:

Added Assets: Some assets were added to give more to the atmosphere. Along with these additions, a couple things were removed as well, such as blood textures. REASON: Textures didn't show up properly and was unsure how to fix. 

New Sounds: Ambience background music changed. New sounds added when items are picked up.

Better Gameplay Functionality: Before update, items had to be acquired in a specific order. After update, items now can be acquired in whatever order to progress.
