My Webcomic actually is the drawn version of a roleplaygame between my best friend and me. We are writing the story with all its lovely characters over a year now (and still not finished haha).
The first time i got hit from her by a great cliffhanger /story changer was the moment I decided to draw it, because i thought: Wow, if you read this as a comic, your brain will go boom.
And now I'm totally obsessed with it XD.
