Yeah, I hate the darkness, even using a Josh's mod for indoor brightness doesn't seem to help with the latest build. It blows.
I mean yeah, it got a bit dark here this afternoon (hell, this whole week been t-storms every afternoon) but they need to tone it down a bit.
Granted I find that to be an excellent time to go mining. Night too. Just put a junk turret or two around your hatch and no one will bother you.
