Real sense of place here! I'm so glad to see you exploring aesthetic elements like sound, visuals and even animations. One thing I would suggest is creating a mini-map. I would load it at the bottom of each page, basically the same image but with a different location indicator for each room. You would have to create the base in one photoshop or illustrator layer, and save the file with the indicator (in an above layer) moved around. A detail like this adds some time to production, but it could only enhance the sense of place. I also look forward to seeing what an inventory system (which I'll demo soon) could add to the experience. Good job!
