Late, but this is what I wished Toby did with every chapter. Chapter 1 had the classic theme, but then chapter 2 should've had a dubstep or techno remix. Chapter 3 could have multiple, since it's also a less story focused chapter. If we get a chapter in the church, we could get a church hymn-esque theme, especially if it's one of the later chapters. We could get like a jungle like remix for Asgore's shop, and then a creepy Gaster remix for the Bunker, if it's a chapter. I think it's legitimately of the only things I'm surprised, and really disappointed, that Toby didn't do with Deltarune. A real missed opportunity.
