Change one thing in deltarune that makes as many characters as possible feel absolutely miserable as much as possible (outside of the weird route)
>no lazy answers like "x murders y" or "kris rapes and mindbreaks a character who isnt noelle" or "the knight stabs the ground frame 1 and the roaring starts and kills every character in the game"
>Changes have to primarily affect lightners, so while something like "jevil escapes his prison and starts fucking shit up" would work for making every ch1 darkner feel miserable, it wouldnt really negatively affect the lightners that much aside from jevil being an inconvenience
