Awesome, thanks for trying it out. The game has a Mac port now! And you're right, there isn't any background music.
The gameplay is a bit vague, so to spoil it a little bit, you want to make the inhabitants angry with the devices around the house to convince them to upgrade to the Froogle alternative, by turning them off. Happiness is shared, so the best way to do it is to focus on one device at a time.
