Honestly, I think karma might be a ditched thing, I seem to remember the dev ended up separating the female protag stuff into its own game instead, wouldn't be surprised if he also just ditched karma. Right now it seems to just trigger flashbacks to the demon times or whatever. Who knows, maybe it'll affect stuff in the future, where MC gets more dommy or something.1. what the fuck does karma does? shouldn't I be doing those scenes no matter what? is there a reason not to sleep with family members in real li... ha sorry, I mean in the game.
2. do choices matter? I've noticed that the game keeps throwing events at me at the start of the game so is the Dialogue progressing on it's on or do I actually need to talk to each character and only then see new stuff? I don't want to miss anything because I went a place and talked to a character I shouldn't or too early.
As for choices, you got some route choices, like Natalie's Femdom or Maledom routes, or the neighbour's/mom's NTR route. Other than that, choices seem to be flavor, like the ones that trigger demon flashbacks.
