JOAJA is a unique parkour map using the best elements from the early days of minecraft parkour and adding its own flair. With 21 massive levels, plenty of Easter eggs. and ranging difficulty, I recommend if you like parkour you should definitely check this one out!
it is recommended that you play with 100 (bright) brightness. Also note that in play testing it was found that this map can be incredibly difficult, and rage inducing for some.
