i went more in depth about this here on tumblr: bug-mode.tumblr.com/post/7523864...
to be clear, i'm not sure if i'm ever going to expand on this, but this was a fun concept to think about!

some character designs.. changed their outfits in accordance to the weather of the area they live in. also first time drawing armor

#sans #papyrus #alphys

here's a simplified concept map! basically you kinda go through the underground backwards. the traits of the areas are combined together to go with the swap au tradition of swapping roles but keeping the core of the characters the same

omg i love the instruments you picked(!) and how the song speeds up gradually (srry i don’t know music terminology)!
(hope you don’t mind me commenting, i just like megalovania covers a lot)
