I'd say writing in chiptune like this is now an almost lost art. The Forgotten World is such a great beginning! So much nostalgic happiness in here... I also love Our Peaceful Home, the music really says it all so well, the couch here, the dinner table over there, a family gathering, the simple vibe is incredible. And Cozy Town really feels like a walk around a small city, people smiling from shops and streets as you pass by... You did a fantastic job translating chiptune into story understanding. I'd say that in Chapter 2 Celia and Rin try to find who sold these books to their families, maybe a mysteriously old bookseller downtown who spent his life collecting tunes from every traveller who crossed paths with this place. They then find that some of these tunes actually belong to people who were once somehow connected — either they were once in love or were very good friends separated by some war. Once the tunes in the books "recognise" each other, they quickly re-bond and stay together as inscriptions in the books ;) Thanks so much for sharing!
