Finally able to atleast finish it on easy.
Luck is a big part of this game, I found the scrap recovery arm way back in sector 2 which gave me heaps of scrap to upgrade.
First 5 times I couldn't even get past the first boss-encounter, now he hardly hit me.
Also a fun fact, after a surrender of a pirate in a non-dangerous zone, I was calmly fixing stuff and healing crew members, even browsing the web a bit for a good minute when suddenly I hear their ship break apart.
I think they got overwhelmed by the flames after my last laser cut.
