As "off" is a fairly common word, the game is almost compulsively referred to as "OFF (game)" instead of its actual title.
There's also Bad Batter for whatever the Batter transforms into during the special ending. Justified in that "badbatteur" is the file name of the picture in the game, and "le batteur" is his name in the original French.
Sampling: Pepper Steak has samples from the jazz song of the same name by the Washboard Rhythm Kings.
Shrug of God: Mortis Ghost has been known for being quite lax when it comes to fan interpretations of his characters and story, encouraging people to come up with answers on their own.
Word of God: Even with Shrug of God in effect above, Mortis has stated that there is a solid underlying story, giving a few details about it.
The Batter didn't transform in the Judge's ending; rather, that's how you see him, considering the monstrous things he's done.
Zacharie, Sugar, Enoch and the Elsens are confirmed to be humans.
The Elsens are all male, as well, and unable to reproduce.
Hugo is not only human, but the one who created the Batter and the Queen, who are not human.
Zacharie himself is good friends with the Judge and Valerie.
All guardians are able to give Zodiac cards (except Hugo), and the Judge gives you one at the beginning of the game, so therefore the Judge is a guardian as well.
When the Batter's profile was created, it was the intention that his eyes were closed under eyebrows, but Mortis Ghost has stated that he finds the "four eyes" theory interesting.
Perhaps as a bit of Ascended Fanon, to thank everyone on tumblr for their help in raising funds to fix his toilet Mortis Ghost drew a picture◊ of the Batter with lots of eyes and Zacharie wearing a huge sweater (which is another common fan theory).
