Interesting, if a little hard to understand at first (especially what you have to do with the objects from the store). Some sound would be cool, particularly when you look at things. "Clicking" is a little tedious, but in this case it's kinda part of the game, so it's hard to come up with a solution for that. The concept fits the theme well though! Good job!
Also, the "hello" was a nice little touch, but I'm not sure if there are any more interactions. I kept trying, but that was the only one I found.
