Honestly if I can get just one other person to like a level I've made then I'm satisfied, but that's beside the point. :P

I think about 20-22 is a good estimate for the age of the average JJ2er, considering that it falls in approximately the median between older JJ2 players (born in 1993 and earlier) and the younger generation who started playing the game more recently (born in 1997 and later).
