Creating your own Theme is easy. Just download this example of a theme and replace the images with your own images of the same size. We recommend making a test image with several obstacle balls overlayed on top of your arena background to give us a sense of what your Theme will look like.
Once you think you have a good Theme, email us (geoarenaonline [at] gmail.com) your theme images along with your in-game username. If we approve your Theme, it will be publicly available soon after and you'll be rewarded with a generous coin gift!
