Hi developer, i have a little ideas for our town , in the ocean we have an island.It's a waste if it's just a decoration .If we have a tunnel, then we would have a mountain or a forest.we can use it to grow the city by doing activities like picking mushrooms, taro, flowers and berries, gingseng,. I saw the left corner where the old man fishing. We can let players emulate a rare fish to chage the goods in town .The game will be more interesting .Thanks for reading my suggestion.
