To add a little bit to the ongoing discussion: I do think that Annie has some hidden agenda as her scene with parents would suggest, her reaction at MC's comment about car and her not telling him about her problems. She's planning to do smth that's probably risky or morally ambigous or both and she needs help or at least moral support of someone she can trust; plus I'm pretty sure she has romantic feelings toward MC (as a gaming scene would suggest), although I think that wasn't the deciding factor in her asking the MC for a road trip. I'm pretty sure that the dev will try to explain her ghosting him (the fault is imo on both sides btw, I don't see him reaching out to her in the past either, they seem to both have stronger or lighter depression that stood on their way to really connect) in a way meant for the player to like her more. I also believe that the similar will happen with Ava and there'll be some kind of redemption arc, although I share the opinion that she is a lost cause as a possible LI. TBH from the 3 women presented here - and I believe all 3 are possible LI - none seems appealing to me. Annie seems the best of the bunch, but I don't find her that interesting. For now I am more interested in how the overall story will develop than in romancing with anyone. I really hope that there will be other LI to choose from.
And regarding the title screen picture, maybe it's one of those games where the picture changes with every update? I hope that's the case.
