Cool Game! I was a bit confused on what the goal of the game was though. The art was really good and I really enjoyed that the items you bought would show up on the shelves the next day. The ability to knock the items over was also a neat touch.
I don't think the game window scaled properly. The shader effects and some other the UI seemed locked to a very low resolution.
Overall, awesome stuff! The sounds and other ambience give off a really creepy vibe.
