Out of curiosity, did you end up getting any game overs while you played? I was a little surprised by just how many negative reviews on Steam were talking about it being impossibly hard or how they did 4 runs and still haven't finished. I haven't found it too difficult so far, but I'm only a couple chapters in, and I know that the resource demands for repairs keeps going up as you progress.
I did 3/4 restarts
1 cause I fucked up and died (ran out of iron and ship when bang)
2nd cause in chapter 2 I fucked up and there was non-stop revolution (didn't understand the worker mechanic)
3rd, I was in chapter 2 and though I could do better.
As I said, you need to solve the 'puzzle' of the game to progress. Early stages you need to manage resources and crew trust and there's plenty of mechanics to be discovered. Once you unlock waste processing and recycling, you don't have to worry about anything as your ship basically becomes self-sustaining. It's a 'survival RTS', so having that ticking timer of the hull is part of the 'puzzle', but I guess plenty of people went into it expecting something a bit more relaxed.
Build an EVA in each section you open, and set it to repair. Only open new sections when you need to, and likewise, defrost people when you need to. Build trust building, water reclamation, waste processing, algae farms etc...and all is groovy. By chapte 4 I wasn't mining anything. Lots of behaviour buildings build, water reclamation (funny when combined with the policy of recycling dead people into 'waste'), farms for food (one whole deck for food processing), and a factor deck with synthesisers to build stuff from waste.
One of the things I liked was having to rebuild decks instead of open new ones to repurpose them as space started running out.
