[Mild spoilers ahead!]
This was quite cute, and the pictures really added to the game. However, there are a few issues.
The first one is the pacing, and I mean this in more ways than 1. First of all, everything happening over the course of 1 day is extremely unbelievable. I would kind of understand if Callie read a book every day, and everything took place in a few day's time, maybe more than a week, though that would still be a bit too quick. However, Callie and someone else falling in love in just 1 day is definitely a bit of a stretch.
