Sorry for the late reply.
I can't stress enough how thankful I am for your feedback about my mistakes! Funny thing is that I tried to avoid those exact kinds of mistakes when making Love, Sam, but I guess i'm too clumsy : ( I'll make sure to fix it on my next update. I admire how thorough you are haha.
And to answer your question about Brian and Sam: Sam could definitely help Brian increase the odds of achieving his goal, but it doesn't dictate Brian's actions toward Sam. Sam is an outsider who is likely just passing by and is a genuinely sweet person who is willing to listen to what he has to say, so it's easier for him to open up to her about himself and his feelings. But Kyle is right about one thing; Brian is not an easy person to read. I intentionally made Brian this way since emotions and relationships are not black and white, just like what Kyle had toward Brian: it could be A or it could be B or it could be little bit of both. So it's up to you to decide what Brian's true intentions were with Sam.
I really enjoy the horror genre in general cuz it is a great conduit for delivering the complexity of human emotions, and through Love, Sam I found a way of expressing my own thoughts on that matter in the most efficient way I can think of. So yes, i'd like to keep making horror games with different stories to tell (maybe even Brian or Stacy's? hehe). It will surely be a fun process with players like yourself there to enjoy them!
