I decided to try to play this game today. I've had to play from "rewind" at least 20 times now. I'm worried that the fight I'm in right now may be a game ender for me.
I can sympathize. Having to replay timed/action sequences gets old fast, and really breaks up the story. If you get irreparably stuck, see if you can find a YouTube playthrough/"Let's Play." I found one last year that was pretty good -- without added commentary by the player, and which showed alternate conversations, alternate paths, alternate endings. Next best thing to being able to play through it yourself.
