The code is still in there, but it's not active. The problem with night is, that it should change something else and not only the lighting...like NPC behaviour or monsters or such. But that would require an additional layer of AI and such and I didn't want to do that. Especially, because this game is tailored to how I play my PRGs. And I usually try to avoid night time in games, because it looks dull and only retricts you in your possibilities. So I asked myself why I should put time and effort into something that actually just annoys me...and decided against it.
For the rain: The rain is just a blitted texture layer with no depth. I works fine in the wilderness, but when being in a town, there are places where this doesn't make sense (i.e. rain in places where none should be). So I decided against that as well.
