Hm... A bit too much.
Well... Your animation style is fantastic. Your voice acting is terrific. And your violence is good. But the premise was crap (the Pope isn't evil). Catholisicm jokes are old, and they suck. However, you made the err of inserting adult themes into violence. Simply put,
sexy + sword + humour = cluster-fuck.
I laud you for your effort and grand achievement, but... it lacked that certain something.
