I played this game for hours yesterday, shot straight into my top 10 games of all time. I love everything about it! The world, the art style, the music, the small story fragments, the exploration! My only complaint, if you can even call it that, is that I want more! I want to know everything about this universe you've created, I want to explore every inch of the store and solve every mystery.
I do also wish there was a wiki or something, I've found a few things that I'm not sure if there's more to do with them or if they're set pieces/dead ends. (SPOILER)The brick wall, the cube, and the ghost in the lower levels.
