Hilarious, at least for someone who played the game. It wasn't too good at first, but the ending... I cried with laughter. Unfortunately, the humor is likely lost on anyone who has not played Rogue Legacy.
Just so everyone who hasn't played the game gets it:
Charon, the guy at the start, takes all your money when you enter the castle, thus "EAT MY GOLD, BITCH!"
Coprolalia (in reality) is a condition where the person subconsciously (meaning doing so without thinking about it or realizing they're doing it) swears often. i.e. a person with coprolalia might say "You're a brilliant cunt" when complementing whoever the "you" is). In the game, it causes #$@%! (or something like that) to appear over your characters head when they're hit.
The trait "Gay" has no phenotypical effect in the game (meaning you can't tell your character's gay by any means other than the character's list of traits), or at least, as far as I can tell.
When you die, the game gives you a rating on how much stuff you killed, thus "the greedy knight"
