The arc of nostalgia is over.

It's about a quarter of an hour if you know what to do. Maybe 30 if you don't know, but some of my players took almost an hour out of the first half because they were spending their time exploring.

You enter the nostalgia house, which is where Gatto grew up. You explore the area, and nostalgia, the overpowering mouse teases you while laughing. But you can become as strong as you want, you will never reach his level, even with max exp.

Once you've visited the house, you go to the basement and explore Gatto's memories of nostalgia and who he really was with a few little puzzles and keyboard mastery passages. And it's sweet and cute, and a little melancholy too.
