I very much liked the game overall, it was phenomenally polished and a great self-contained story.
I know it seems like an inconsequential detail, but I genuinely was glad that there was an elevator and also a story reason as to why the character didn't use it. If there was just the elevator there but you couldn't interact with it, or no elevator at all in a six story building, I would have been thinking about that the entire play-through.
Like others have mentioned, the field of vision changing and the sound design when in a panic really brought me into it as a player. I was honestly worried that I would have to go back up after taking the picture, because I was thinking to myself "Well what if my phone put the wrong timestamp on this picture and I didn't actually take it this morning."
I think this is a perfect little look into a small window of someones life and seeing their struggles. Struggles that an average passerby, coworker, or friend wouldn't normally see or often even consider.
