Thanks to @edmcnierney we are now setup on the XPrize GitHub organization. I've pushed the first, very early code for our entry here: https://github.com/XPRIZE/GLEXP-Team-GLEXP-Team-The-Linguaculturalists
This is still very early work, mostly in the plumbing level of the code as I learn my way around Android and AndEngine, so don't expect much to work yet. Currently it loads a map from using a texture image and a TMX file, and then lets you place a few items on that map. The final goals are described on the GitHub page, so you can get an idea of where it's going.
We will be running this as a typical open source project, so anybody can start looking at, playing with, and we hope contributing to the code. You should be able to
git clone the repo and load it directly into Android Studio. If that doesn't work for you for some reason, please let me know and I'll try and get it fixed.
