Ah thank you so much, that’s sweet of you to say! <3
Yes! To unlock Ending 6 (which leads to epilogues) you need to pass both stat checks, as in, ideally you should pick either Chaos or Brute Force instead of balancing both (which is an oversight on my part! In my future games, I’ll try to add an extra option for a balanced route, but it wasn't possible here because the stat points can differ greatly depending on the branches).
So, basically, you need over 6 points for altruism OR self-serving stat to pass the first check, and over 6 points for Chaos OR Brute Force to pass the second stat check (I lowered the original threshold after the initial feedback, so it should be easy now to max the stat even if you skip some relevant choices, as long as you stay on a single stat route. Though do let me know if that’s not the case, and I’ll see what I can do to make it easier).
As for the plot points, you can get to Ending 6 in the same place you got Ending 5, only that if you have maxed out the second stat (Chaos or Brute Force), one of two options will be unlocked for you:
“...to subdue or wipe out the constructs.” for Brute Force
or
“...to seize and try to disarm the stone.” for Chaos.
Picking whichever of the two will lead you to Ending 6. Hope that helps!
