I actually like the door death…
Wait hear me out...
I don't think it fully makes sense but I've always seen it as Ashley wanted to open the door, she just hesitated because she was traumatised after Chris was actually willing to shoot her, even if she'd told him to kill her as her last wish. She'd just had a near death experience and I think that made her value her own life a lot more.
So when there's a wendigo right behind Chris she has two choices: open the door, risk dying and save the guy she has a crush on or leave him outside to save herself. At first she was being selfish, but I don't think she intentionally left him to die. I think she just didn't get to the door in time.
The trophy name also makes me think that. It's called "Nightmare on Ash Street" instead of "Ashley Snaps," which makes it seem like it wasn't done out of resentment. The remake makes this a bit clearer too, and it's basically confirmed by the trophy description: "Ashley hesitated and failed to let Chris inside in time."
Anyway I actually like this outcome because it makes the game more difficult. Until Dawn was the first PS5 game I ever played and I still got the trophy for not failing any of Mike's QTEs while chasing Jess. I imagine it's even easier for people who've already played other PS5 games and are used to the controller.
Almost everyone survived in my playthrough, but I failed the very last Don't Move segment because I actually held the controller the whole time lol so Sam died 💔. So in what's otherwise a pretty easy game, I like that there's a consequence that's harder to predict.
I almost got Ashley killed because I like Chris a bit more. Once it was revealed the gun wasn't loaded I didn't think much of it. I feel like this moment shows the butterfly effect really well! Everyone's been through something incredibly traumatic, so they're not going to make perfect decisions. Because of that I actually think it's pretty realistic.
