hello, moderators of Labyrinthine, for Individual Level leaderboard, for every level done individually there, you must fill the "INDIVIDUAL LEVEL CATEGORIES" by going into Edit Game - Categories. You will find the "INDIVIDUAL LEVEL CATEGORIES" down below. There must be a difficulty there (or multiple), I guess the basic category could be named Any%. Thanks!
