I really do appreciate all the advice and I do find a lot of it helpful!
I wasn't actually that obsessed with getting the trophy but with the way everyone's been so helpful, I do intend to see it through eventually so all your efforts don't go to waste.
Score Attack aside, my feelings are really mixed about this game. I think it's well-made but I almost feel bad that all the talent and effort went to waste (IMO) on a really annoying & lame story and characters that I don't find interesting at all. I know some people think the story is really awesome but I find unnecessary suspense incredibly irritating, and I'm not a sci-fi nut but the story doesn't hang together at all.
