A game from me to you~

Alright, I figured out what my character is exactly. He is the butler who guards the Mansion of :3, in which he guards the eternal slumber of the possibly hermaphroditic goddess of the forgotten wisdom of the nether regions and the dark side of the moon using some of the knowledge he has acquired from it. However, the reason we'll never meet this character is despite the player's efforts, the door will remain sealed.

Also, one of the attacks he uses is a giant ":3" filling up the screen.
