I also bought this game as part of the humble indie bundle, but I'm unable to use it. I can't change the game from full screen to windowed because it won't let me click "yes" to accept. I also can't exit the game normally. I tried to remove all the joypad key bindings, but I'm not sure how to do that exactly. I click on the binding, it flashes like it's waiting for input, and I tried hitting escape, and different letters and keys, but nothing seems to work. I also tried manually editing them in the XML file with no luck. I was really excited to play this game, but now I'm wondering if I'm ever going to be able to.
