I didnt use deltatime, materials in the definitions of each model, nor modelstates. So its needs a lot of fixes/improvements.
Also I'm still unable to correctly texture map a sphere

But I made it in a couple of hours.
I will like to invite you to help me finish with ideas/suggestions to improve the use "correct" use of ZGE's features in order to complete it.
Also if the result is good, could be a good to make a tutorial or add it to the examples in Zge's projects.
