Add seasons (spring summer autumn winter)
Day n night time (you can on/off if someone dont like it)
I dont like that purple background maybe you can change it in to sky or something like that

Thats all.

Winter should be difficult, because new textures would be needed

Autumn and spring should be possible with a shader.

What about the blue background as you can see it in this image?


Both, seasons and day/night times will need an huge amount of additional graphics. Not only that's a lot of work, but also it would be too much graphics to be loaded all at the same time. That's why we changed season for the whole game in the past. It may be possible to reload specific graphics when needed, but that may take some seconds, so we shouldn't to it too often. Finally, we don't know yet how we handle seasons, but it's much more likely that we will add them than the idea with day/night.
