Just noodling with an idea for the top floor, since we have no concepts of that area yet strangely. Did a quick doodle experimenting with keeping the space fairly empty and bleak, with soft light everywhere. I remembered the opening scene of 28 Days Later, which is an abandoned hospital that is still clean and very light. The piercing silence and unreadable environment were very eery and creepy. It was the complete opposite of the total darkness approach some horror things go for, but just as scary I thought.
