Don't usually do this sort of thing, but I felt so strongly about it I decided to make an account to leave a comment here..
Spoilers I guess,
I really don't know how to feel after it, and that bugs me to an extent. At my stage in life I don't really find game narratives to be particularly gripping, or plot twists to have any real bite which is why it totally shocked me when I found myself at full attention, absolutely enthralled in this narrative, fully invested and hopeful for what these two might become while being just as equally petrified, worried and unnerved for what the horrible eventual truth about Lee could possibly be when it finally decides to rear it's ugly head.
I think most people will clue in early on somethings going to happen and it just makes it all the more tragic as you really grow to love these two, I've always found Romance in video games to feel really plastic and meaningless, nothing ever felt believably genuine because of how in service of the plot it always felt and yet with this it feels so real and I really can't pin it on anything - but if I were to try I think it'd be in part due to all those fantastically mellow intimate moments we get throughout the story, despite how little things may be progressing literally and physically in those moments the growing bond I interpret from them feels deeply authentic and meaningful, more than anything I've experienced before - maybe there's a whole genre for this that's lost on me and I just have poor taste in games but it really stuck with me after.
I can't describe how badly I wanted them to win out in the end, and I guess technically they can if you choose to but after immersing yourself so much into the narrative and characters it just feels so wrong on every level to choose that option, I'd be a liar though if I said watching Lee drill his brains out didn't hit me like a train.
Probably wasn't helped by Angel (Angela?) learning no one was ever trying to contact her while she was missing, this plot really doesn't pull any of it's punches.
I really don't want this to be the end. I think there is more to be told here so I guess the point to this all, my silly little plea to the developer: please continue this story. Despite what he claimed I never believed Lee would be able to walk away from this unaffected and I'd love to see and suffer through it all in a continuation, I think if the acceptance ending were ever to run its course as Lee becomes more grounded in Angels company in a somewhat more healthy and normalized environment the gravity of what he did would set in, perhaps in a setting that flips the character perspectives to explore his psyche as it slowly unravels while impossibly trying to make this new life work would be an experience just as equally gripping and emotionally confusing as this game was.
Regardless,
Take this whole giant multi-paragraph ramble to be an overcomplicated compliment - congratulations your game broke me, and whatever comes next from you I'll be there waiting for it.
