I just finished playing both routes. This game combined with the somber soundtrack feels like taking a stroll outside in a place you'll never be able to come back to. I don't really know how to describe it, but the lingering sense of hopelessness brought these characters together very nicely. It definitely gave me a lot to think about. I think it was paced pretty well, too.
I'm sending this game to a couple friends; hopefully they'll take it slow as I did and get to experience what the story for what it really is. c:
