Actually, there are almost 7 endings...
since v1.0.2 (Now It's v1.0.4)
def is_all_end_flags(): return (persistent.safe_end and persistent.pm_appeared and persistent.court_bad_end and persistent.court_win_end and persistent.love_brain_price_end and persistent.love_brain_good_end and persistent.love_brain_special_end2)
if you passed is_all_end_flags, there will be something special :)
By the way, regarding the music, I've already made a horrible one for v1.1
But for v1.0.x, I think it might should be a softly & lovely one.
