Bad news :(I have been very busy and I will continue to be for some time. I won't be able to work on the Stellar GUI on a couple of months. If anyone is interested in contributing and is lost, please contact me, I can update you on what has to be done. firstname.lastname@example.org
Good news!opon4 continues working on the awesome SGE so you should be following the project progress on stellarengine.nongnu.org. He will be updating often and preparing a set of separated tools for game development that will help de game development.
Hugs and wish to be back soon!
