>>40154023Going to the start of the game is obvious, we all played it so we know what choicces need to be made. It's also a ridiculously long time for you to write about unless you plan to skip huge lengths of time which isn't good.
The most important aspect of a groundhog DAY is that it's supposed to be a DAY that's repeated over and over again and im not sure how you'd work a feel good into the day of the school shooting while resolving the story in a satisfying way. I think the concept you're looking at is inherently flawed and would at best be very bitter and a little sweet.
You could have the groundhog day take place at prom but then you dont have the emotional impact or a good reason to groundhog day.
