The buildings didn't seem to do anything until I bought the restaurant and then the newspaper started making money but the restaurant didn't. I agree that the music needs a longer loop because it's perfect for the game but such a short loop becomes annoying. I really like the art and the general idea of the game. It just needs some more refining. Also, since everything else is controlled with the mouse I would suggest a clickable button to pull up the phone, rather than the Tab key.
