great game! really nice graphics, and I really liked the cars moving in the streets. When I saw the theme, one of the first ideas that came in my head was to make a city builder, but I found it too hard to make, and I abandoned that idea. It is nice to see someone really doing it. Well done!
After reaching some high level houses, I couldn't spend my income even when I tried as hard as I could, the income was too large, that even when I tried, it was still going up like crazy.
Except from that balancing issue, the game was wonderful, and the assets were really really nice, good job!
