Hello Mozos, the wait is finally over! You can now buy Roboban: Colors and rack your brains with all 90 levels of the game. I'm also pleased to announce that the game can now also be played on Mac devices. It's something that was planned for after the game's release but I've managed to get it ready before then. As for the challenge to appear in the credits of the game, I'm ending it with this news. If you have completed the challenge you will see your name at the bottom of the credits page. If you have completed it, but you don't appear, feel free to write me on the Steam forum or on Twitter and we'll check it out. And finally, if during your game you find a bug or have any suggestions for improvement, please contact me through the means mentioned above and we'll see what we can do. Enjoy, have fun and thank you all!
