Hello pixeldrop!
Thank you for your message. Unfortunately, the game was not designed to play with a controller, that's why you are having trouble with the input mapping. However, we will try to implement a fix for this. We'll let you know soon. With respect to the first room, are the 0's you are seeing all over the screen? Or are they images? You are supposed to find a barrier at first with blank spheres and symbols but it should go away on its own after a few seconds. What operating system are you using? Could you post a picture? We will make tests on Windows right away to see if we can find something.
