I do like the idea of changing seasons though. They might really help to keep things fresh. I am not sure whether you have already implemented that, but the probability of certain needs of the villagers could be changing according to the seasons. Like in spring people think more about finding love, while in summer/autumn the harvest is usually more important to them.
I could definitely see myself revisit the game in the future. And I am looking forward to seeing what kind of changes you are going to implement.
