I really enjoyed this game, it was like a facebook game except it didn't ask me to buy virtual coins to speed up building.
One thing that really annoyed me though, and has been mentioned many times, is the lack of a "move building" feature. Destroying a building and firing everyone who worked there just because you built it one tile out of place is pretty infuriating. The lack of this feature takes 1 star off my rating, I hope it gets fixed if you make a sequel.
