Expert mode DOES need a overhaul, since all the resources deplete superfast, but the dev said they're gonna balance it, thankfully. Once you start out, you gotta IMMEDIATELY grab the extra fuel cans from the base. You do the first mission, upgrade your ship to hold more fuel, fuel it up.
Went to the fuel station, did the tasks there, but how do you get more ores? Didnt see any of the drills mining them. Not sure on that part.
The oxygen station seems to be somewhat bugged? I saved probably, halfway through doing the tasks, left for the day, came back, and now its just.. stuck on 18/36? Cant unlock the other rooms since, even if i plant and harvest and plant and harvest, its still stuck at 18/36. Seem to be softlocked unless theres more stuff to do there, which im not sure about.
