I have an idea!
if the public demo map is 8 notebooks, it's the closest to 9 notebooks which is only in f3, so we could act like public demo map is 9 notebooks/f3! There exists a bbp inspired mod for android for f1 but I suggest put both screen resolution apks, and then you could put the baldis basics classic apk for f2 cause f2 has 7 notebooks and so does baldis basics classic!
Do i have a good idea?
