First off, I agree with another review's suggestion to play this at night; I happened to play it shortly before bed and that fit the vibe perfectly.
This thoughtful, cozy game digs into something I think about almost every time I take the train -- how I'm intersecting with strangers, seeing a sliver of their lives, and going on my way. It's a grounding experience in shared humanity, and the aesthetics and writing fit that feeling perfectly. It feels good to have pleasant encounters, but also there's a certain sadness to never being able to know everyone more deeply.
Very nice art and music choices to go with the full voice acting. Thanks for putting this little experience into the world.
