# SIDE/TOP CHARACTERS
# Author Molegato
# Version 2.2
# (V1 was called 'Lateral Characters')
#------------------------------------------------------------------------------
# Only characters with @ in their name will be sideview
# Only characters with # in their name will be topview
# A character with both in the name will be sideview, but will rotate
# when moving diagonally. Great for flying/diving sideview
