How to play: Everything is controlled via the mouse.
Jobs: Every job has its perks, except "Unemployed". Experiment to see what works best. "Unemployed" makes for a harder game if you choose it for you character, though you can't control what survivors on your ship did before you were all stranded.
Fire: Thankfully, SigMo is warm enough of a planet that you won't need a fire to keep you warm. Though the fire does not directly benefit your team, it can definitely help keep predatory animals away during the night that might otherwise try to make their way into your camp.
