I remember playing it long time ago caught my attention only to bump into it now. Kind of would love all the poses to be available for all girls. Like beating them would unlock the poses for the other girls.
or some kind of pose unlocking, although majority of the left side for the girl to undress seemed to be unaccesable
at the beginning not sure how or why but I 2 shot the girl in costume B
with the normal pistol like ???? but after 5 more goes trying not to 2shot it went as it should be
