Recently modeled & textured SumWars character by Evil_E
A new release (0.5.1) has been recently uploaded and the next release is being discussed.
One quite important planned feature is an OSX port, as there are at least two (if I recall correctly) who use that operating system to produce art for the game. CMake is used for compiling on Linux, so I suspect that porting might be in fact trivial. If you can help with the task, please report to their forums/irc! :)
