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.

Very nice little idle game, my lemonade stand manager was working very fast! Progression was paced well, would be nice to see an income per second stat when hovering over the buildings for a little more info if you were looking to develop any further. The music was nice, but it could have used a longer loop as it felt a little repetitive after a while. The clicking sound effect as money came in was very satisfying
