This is such a nice game! As someone who loves taking long walks for similar reasons to you, getting to take a promenade alongside a city I've never seen before is an amazing experience. Something that is missed by the mainstream ways of "digital tourism" (like reading about the place online or Google Maps) is that a city is borne out of the personal attachments to it by its citizens, by their memories and experiences in it. In this game, I feel, you manage to provide this soul, giving a life to Coruña that we would otherwise not be aware of.
Coruña seems like a very beautiful city and you have very beautiful memories tied to this place. Wish you all the best in your gamedev career and life in general!
