Stunning art, really. I played download as the web version crashed on me.
I really liked the idea, and the subtle whispers you hear. It got somewhat repetitive, but that's mostly because the walking speed while on the neighborhood felt excruciatingly slow to me. Maybe if I could walk faster or if after delivering to the last neighbor it already put you home, I would felt more compelled by the story.
One minor thing would be being able to finish a dialogue without skipping it. I thought the letters appeared way too slow, and when I tried to press F so they could load faster it already skip the dialogue or went to the next window. I wanted to read some of the dialogues with the neighbors that I ended skipping.
Regarding audio I got no remarks. The soundtrack showing "ordinary" day to day is nice.
I really liked the art, it's enthralling! It really gives this vibe or eerily ordinary. An amazing atmosphere overall. Good job!
