Reputation

Reputation is how well your village is doing. If your repuation is below 50, your people will stop doing their work and their houses will deteriorate over time.

Increasing Reputation
If your reputation is decreasing, there are 2 possible explanations. The first one, and the simpler one, if you do not have enough money to pay your workers, they will decrease your reputation. If you have money however, you will have to find the source of this problem. Look for one of the houses with a red background over the center. This occurs because that specific house cannot find any Markets. If there is a market nearby, make sure that the market sells the specific type of food that house needs (vegetables for workers, apples / meat for researchers, and meals for engineers).

Deteriorating Houses
Once your reputation is lower than 50, your houses will start to deteriorate. To stop this, you can short-term prevent this by building more houses, however this can waste resources and time. The better long-term solution is to increase your reputation above 50.
