I replayed the demo and honestly, I didn't expect to have new encounters. For some reason, there are two LIs unlocked that were never there on my first runs (that happened last year). I don't recall any decisions with a heart icon, but I'm assuming it was because of my moral alignment (went for pure altruistic)? I'm pleasantly surprised coz I loved the new encounters in the end of the demo.
I can't wait to see more of this!
