This is quite good! It gave me enough info to get an idea of what's happening while leaving me with many, many questions. What exactly is this tragedy that's keeping Naomi up? Who was that woman, and what's she talking about? Why is Naomi so gosh darn hungry?
It's tonally really well constructed. The rain in the background, the little moments of self reflection, some of the vague and ominous later dialogue... it all really comes together. That heart beat sound really sent me for a loop in particular; I didn't even realize that was just a sound in the game at first. The shift in how the optional interactions are written before and after the power goes out is also a nice touch.
This had my attention grasped very firmly, and for good reason! Nice work.
