Planet temperatures have received an overhaul, thanks to some great feedback from players.
I tried to make it a bit more logical, though it could hardly be considered scientifically accurate. Here's what has changed:
Night Time:
At night planet temperatures will drop. How much will depend on what type of planet it is. If it is a planet with a "normal" atmosphere, then the temperature will cool down by about half. There are some other variables at play here, but that's the rough idea.
Planets with a vaporous atmosphere will only get a little cooler at night, most of the heat being retained in the dense moisture.
Planets with no atmosphere will get extremely cold at night, so be prepared to experience some interesting changes to gameplay.
Caves:
Caves will also adjust the temperature. On cold planets (less than 200 Kelvin) the temperature will actually increase, thanks to the warmth of the planet's inner workings.
On other planets (above 200 Kelvin) the temperature will drop, but not by that much, keeping it at a minimum of 200.
Tutorial:
I was also able to address some issues with the tutorial. You will no longer be able to exit the console before going into orbit around a planet, as this caused strange issues with the tutorial window.
Also, when landing on your very first planet, I have made sure to make it day-time, so new players are not left in the dark.
