Adding the season and weather
:(It's a little boring to see the same map everytime, maybe we can add the season and weather for fun.
For example, in spring, the efficiency of reforester will be doubled. In summer, the efficiency of worker will be a little lower because of high temperature. Then, worker can drink bear or juice to recover. In that case, we can have new buildings such as fruit cutter, Juice House.
And in fall, the efficiency of farm will be doubled. Or, each fall season, the tree and fish will be re-deposited a little bit.
The weather section can be randomly, like the same as I mentioned in seasons, the efficiency can be adjusted. Besides, certain surprise could happen due to the weather, like damager from flood or work stopped for a while because of tornado.
I think it will be fun if you upgrade those awesome stuff.;)
