Caved and bought it. I’m having a great time so far after 3 hours. You really need good faith for the first two hours as a player to figure out what’s going on and get used to the control scheme, but after that it’s all good.
I have a manual solar panel connecting to a couple of machines in vacuum, the portable oxygen barrel in a sealed room, and then my latest project is making an airlock. I’m trying to do it with zero engineering experience and as little use of the wiki as possible. So far I have the two airlock doors and an active vent connected by pipes to inside the sealed room with the oxygen. So I am able to pressurize inside the airlock, but can’t depressurize without just opening the outer airlock door. I’m sure there’s stuff I am missing I will check out soon, but at least it works!
