I gotta be doing something wrong because i can't even get through the first rover section. Normally i fail because of water but the last time was because of air. I jsut can't seem to get the balance right and it always seems SO close it feels like i'm doing something wrong
If you're running out of water, you need to make sure you stock up as much as possible before leaving, which requires you to have NOT consumed all of the non-infinite water before you leave (from the Extract Water action). If you're running out of air then you just need to use the Fill Air Tank action more often/earlier.
If you need more advice, I recommend joining the Discord. There's a lot of people active on there, including several who are trying to optimise speed runs.
