That was just me being a worrywort. It turned out to be nothing. Luckily, I went in more or less not knowing much. I tend to fret a bit too much about avoiding spoilers because of a few negative experiences in the past, but you didn't actually spoil anything. I was just being paranoid (BTW, I didn't mean to reprimand you for that comment and I hope that's not how it came across). No apology needed.
I think I assumed the Carruth reference meant time travel? I haven't seen Primer or Upstream Color, but I knew that time travel was involved in the case of the former film and I made the leap to wondering if that was, like, a secret gameplay mechanic or something…which evidently wasn't the case. Sorry for unnecessarily worrying about it and mentioning it at all.
