You are way to exaggerating. Your entry for the summer 2007 contest is remarked as "free" to everyone on the Acknex Ressource Site. Your game has no license file included which explicitely denies the usage of your content. The terms of the contest included that all entries will be open to the public "as they are". I understand that you claim your copyright, but please remember the circumstance under which you released the game.

Please re-read the moderator's guidelines and add the removed text from the original post - otherwise he can't get help on his problem.
