Planet of Ash isn’t structured much like Adastra; it has several routes and multiple potential endings each, so there are a lot of important choices. (Also, Adastra only has six choices if I remember correctly, but several of them factor into which ending you get.)
I mean, it's been a long time since I played Adastra, but I can assure you that if it only had 6 choices I absolutely wouldn't have played it. And when I did, the only relevant choice was whether your name was wiped from the database or not.
