I liked the story but was a little disappointed you don't have all answers.
I kinda get what bbyfdfd means I think. I think this is like a level one story, stuff happened ect. Maybe because the author wants to give himself some margin some elements don't click.
For example there's apparently lots of "survivors" but they don't interact. But it's justified in the story however I don't feel great.
It feels more like a family revenge reborn. However the space power are reasonable and the pace is good.
My only letdown is the reuse of the same trope, it's just one or two who repeat and everything else is fine.
To finish I'm glad there's no bull karma threads she's just unlucky.
