Slight Spoilers: I've played this game a few times through now, haven't sacrificed anything with the knife. Won twice, chose different options each time.
INCREDIBLE atmosphere! Sfx for the other guy gave me chills. I haven't felt so immersed in a video game in ages. Please expand on this, I'd love to know more about what's going on, or even just more cardplay! Bless you for this short, yet intriging game.
