The prep for the festival is Act 1. With the first day of the festival, Act 1 ends. So its not that much ahead of you.

I’ve looked at my Steam page and in my Review 8 years ago, I actually wrote that the first Act is kinda “uninteresting”. My playtime is clocked in at 45 Minutes, for the original game. The plus version I played on Switch but the main story is the same.
