i recommend neutral first
I would do neutral, but I would decide to kill all the major characters. But since I already spared toriel, I'll just stick to my true pacifist route first because that's how the game is supposed to be played.
Some things I noticed during my playthrough up to snowdin town
-Didn't encounter a single vegetoid
-You can actually solve the puzzle where you have to turn the x's into o's without papyrus' help
-Got a strange call from Sans asking if my refrigerator was working
-During the greater dog fight, he only used the spear attack once, making this fight very easy.
