Well, I much prefer to have a story that doesn't retcon itself in a patch because the dev made the literal murderer Sans into a blind pussy because he was actually awesome.
Oh, and how the game handles the Earthbound section I've grown to hate. Shows how much you aren't allowed to have fun killing. Much like how Underfell Sans was stripped of his "murder is fun" angle. Let me murder in a UTDR game for fun, damnit.
