I have no idea how search algorithms kept this from me for so many years. Very cool.
I downloaded it just to take a look, I noticed a server and a client. Does this support multiplayer?
Also, I was reading the attached licensing document and saw under the "Do Not" section:
"Reproduce, copy, distribute, resell or otherwise use the Software for any commercial purpose"
Does that mean no commercial games or no commercialization of the software outside making a game? (just curious)
