I just kept going back to Galvey (the first mission / planet) and picking up more plants to grind for easy profit. I tried doing it with Karbyne (the second mission / planet) at first but realized I was either stagnating with money (because I kept spending it on fuel and oxygen over and over again) or actively losing money. Then the last mission to Centarah was kind of uneventful.
Overall, nice concept, though there isn’t really much to do content wise.
mad that I lost 40 units of oxygen one time >:(
