It's still not working? I was wrong before, I think - the image is in a supported format but you are accessing it with the wrong name, for instance, in Zona.java: case 0: setBackground("D1.jpg"); ... but the filename is "D1.JPG" not "D1.jpg". On the gallery filenames will be case-sensitive!! There are a whole bunch of similar problems.

There's still an exception. At Zona.cambiaImagen(Zona.java:142) it looks you are setting the background image, however, the image format is not supported. (It might be supported on some systems, but not on others - it's best to use formats such as PNG which are fairly universal).

I agree - it looks really nice, and is a good idea, but when a ball goes just past the point at which you might hit it it is suddenly game over. It would be good if it was just a bit more lenient!

I don't get it. it seems I can walk around and blow bubbles... but what am I meant to do? And what's with the turbo C background?
