You can generally count on me to get caught up in the music! And this track is SO good!!! I guess no matter how much I feel like I've changed for other reasons, it's nice to know that one thing has definitely stayed the same.
For the record, undertale also swears. It’s just much more hidden then deltarune, sans can swear on genocide after you spare him and flowey can swear after an enough nuetral routes are committed, because he assumes you’re just trying to ring out as much dialogue out of him as possible which makes him angry. There’s a lot more but those are what came to mind. I guess with deltarune Toby decided to be much less subtle
Sans and Flowey in those instances only say "pissed" which counts as like a low tier swear at worst imo "ass" is never used in Undertale (though Undyne skirts around using it in a phone call)
