Awesome game! Crossing fingers that this is going to see a full commercial release sometime in the future. The theme and execution is great, I really like how organic the city looks.
I downloaded the game to experiment a bit and doubled the score the Factory produces. I find it much more "competitive" with the other pieces this way. Maybe I'm missing something, but its much harder to place well then say Habitats, and I think it'd be better if their score reflected that.
