I'm glad to have surprised you then! Honestly, I realize the game isn't everyone's cup of tea, whether it's the genre, two-character POV, whatever., but I'm glad people are trying it out to see what they think.
On partners and love interests, great question. My current plan is to avoid a traditional "primary love interest" sort of dynamic in part because the endings I have planned deal more with Alex's decisions regarding Mayhew's offer, what he discovers, and what he decides to do with the information he learns. Who winds up being by Alex's side at the end will depend on those choices. Some choices are going to simply be incompatible with some of the characters' personalities. At least, that's my plan.
On Connor/Seth/jealousy, I hope you'll forgive me but I'm actually tickled people are having this reaction. On one hand, I want people to like Seth, too, and I hope that will come along as his character is better developed and gains more depth. But, on the other, I'm glad some people are having that jealous reaction as it was very much intended for those who want to play it that way. And we'll see how that unfolds but it is very intentional and there is a direction it is heading -- one that I think will make most people happy.
