First of all: Thank you for your positive review! I'm a little surprised, 'cause I thought the ending comes a bit too early and the story could've "developed" more.

To your question: It's the German book cover. That is because this flash was originally in German (I originally never intended to publish it). When I decided to submit it to newgrounds, I redraw the German writings and redubbed the whole thing. But I was too lazy to replace the book cover. That's why it's in German. No further significance. ;)

I could upload the German Version, but I doubt there'll be positive response.

Thank you very much. :)
Though I must say, as is said in the credits, Jens is not my invention. The first of a long series of Jens-Comics was drawn about two years ago by a good friend of mine. Since then I also drew lots of comics and small .gif animations, even 3D-renderings (yes, they love Jens. :> ), then decided to make this flash.
