To anybody who asks how to play custom maps, its for android becuz i dont have access to pc at time
1. Get a map/maps
2. Unzip mappack or whatever is in this path: 0/android/data/com.JohnsterSpaceGames.BaldisFunNewSchoolPlusUltimateEdition/files/Follr Customizer
Then make sure that maps having only 1 layer, in short: files/[name of map], not like: files/blah/mapname
