??. Egg Room (DELTARUNE Chapter 5 Soundtrack) - Toby Fox..?
Unlike other Chapters, the song title for the Chapter 5 Egg Room does not contain "man". Instead, this song is called "deltarune_piano_collections_by_trevor_alan_gomes.ogg" in the game's files. Assumedly, this means that this song was arranged by Trevor Alan Gomes, creator of the DELTARUNE Piano Collections.
Man, this Egg Room really messed me up, dude. That was so sad, especially as someone who is super nostalgic for Chapter 1, as I played it back when I was like, 7, and I'm like 15 now! I thought I'd see some tragic lore about Kris or the Dessappearance but instead I was gut punched right in the feels of my own nostalgia. I hope we see the Man again, I can't let go just yet.
