Just a quick little post here. A week ago a programmer named Omer Bahri Gordebak started making a clone of my game. So I contacted him and gave him the source code of my game. After that I agreed that he can open a SourceForge project so that everyone can work on the game. The game is now under the GPLv3 licence and everyone who wants to add stuff to it (ether engine, gfx or sound) should go to the SourceForge site. I hope that some of you will add something to the game.
