Great art in this game! You've built up a really good spooky feeling with the sound as well. I went to all the houses but couldn't proceed after that. Not sure if it's a bug or I took a wrong turn somewhere in the story.
Maybe I did finish it then? After I went to the house in the most bottom right all I could see was a single house I couldn't click on. Assumed that wasn't the end because of no end screen or anything that felt like it concluded the story.
