Ok now it works :) You should add some sort of indication, what you have to do at the start of the game. There should be a way to close the game, because I had to press Alt+F4 to get rid of it. I couldn't do it any other way, because the mouse cursor was stuck in the jail. Also, I didn't understand why the game had reversed text, but otherwise, a cool idea.
