Well I went to check out the game, and then played for at least two hours. The city is limited, but all the upgrades and such make a compelling reason to keep advancing.
Please add some autosaves after major events.
The look and feel of this game makes me want more, even before reaching the end of what is available.
I have to say that getting gold might be a bit too easy. Maybe reduce the money reward, supplying water became an issue a few times, but I never had a problem paying for anything.
-Started a new game and realized I was playing on easy the first time. It's a little more balanced on normal. :)
