Ok, so basically, you just have to not talk to The Unctuous Doberman. He was just there for a bit of worldbuilding and isn't necessary to the story, but if you talk to him everything will break. Basically do everything you want to do first, and then talk to NPC Base, that should give you the best result. The way to get the ending does involve your arms and giving/not giving them to people, so also keep that in mind.
Also, thanks for the follow, glad you enjoyed!
