I thoroughly enjoyed this game. It's very clear how much effort was put into this, and I think the choice to set it in Japan is very interesting. It's also amazing that all the graphics were totally original; this is especially impressive because of how haunting the pixel-made art was.
This is unrelated to the game, but I laughed a lot when I saw that the realtors were from "Furukawa Housing" since one of my favorite Japanese indie artists is Furukawa Honpo. Though, he does sometimes write his name as Fullkawa instead.
Anyways, just thought I'd share! Keep up the good work!
