First the Positive: I have been reading this since .1 and have really enjoyed it. I like the characters, the story was fun, and I looked forward to releases. Sophia if fun, and I am enjoying the mystery of Abby. This is one of the ones I have read again with each update.
The Negative: Why is everyone rewriting their stories from the beginning all of the sudden! Especially when it ended on a cliffhanger. I will hope the new story and character models aren't so different that A Second Chance V1 forever ends on a cliffhanger. As I have already said once this week, people liked this story, please don't remove the funny interesting bits and make it generic. At least none of them did anything crazy early, and they have only gotten a moderate amount of character development, so there isn't as much to lose, and you seem to be rewriting everything.
The warning: if you add the potion as stated above, even with just two girls that's four versions of every scene it might affect, and 9 versions with three girls. It can get out of hand really quickly
I guess what I am saying is I would like to be able to skip 4.5, start reading again with .5, and still recognize the characters and story going forward. Otherwise it is really "A Third Chance"
