The game is emotional but it mainly comes from two tragic sequences.
The sub-timeline of trying to save Chloes biological father and the ending.
i stumbled on a video on youtube for a happy ending to the game.

Someone commented that they didn't think this ending should be easy to get possibly require a second playthrough. and the videoposter agreed, saying one should have to 100% the game to get it.

I only kind of agree that it should be a second playthrough.
This is something that would be very difficult/expensive to achieve (as in develop) but what bothered me is Max never tries to find the limits of her power. (Granted, till the end she has no indication that there is any.)
In the timeline where she saves Chloes biological father, she tries it once and gives up. i was going "how about establishing some connection? trying to give herself something to act on to stop Chloes accident?"
She does have access to her 13 year old self. She could have made it an annual thing that she came back and stayed with the Price family around that date and that she takes a photo each year. Or for a lesser change that she at least called Chloe regularly (with a photo before each phonecall.)
Either of these would have allowed her to travel back and influence Chloe and try to avert her accident, with the old photo incase she needs to change more.
And at this point she has no idea that travelling too much is a bad idea.
In short, Max doesn't try to get it right.
