You have a bug where adding a player doesn't work the first time (from https://jrimbault.io/citation_needed/) as it redirects to https://jrimbault.io/citation_needed/?# and clears the player list. Then it works.
It's tiny, it's fun, it's enough. Keyword : enough. Yes I could add a preventDefault, but I don't care. Really, I only entered the names of my friends once, it has been in my localStorage since, and it's only really meant to be used by me.
Fixed it.
