Nice sketches! I really hope you'll be able to recover your files...
Oh gee/great, another MG/GAE debate? Hopefully not.
Anyways, there will be a changelog once 3.4.0 is released. Latest new "big" MG things are FTP transfer support and integrated IRC...mainly MG has more "improvements" than new features, but that might change later.
Personally, if you recover your files, I think you should maybe make two separate versions. MG one with balance updates and new units, and GAE with all that + new features, I guess. (wait for GAE 0.33)
Also having a MG version would be good because people would probably also try it out on GAE... (I would.) Then of course, I bet people would like to try woodsmen with each other. (Last version has some bugs and then it gets out of synch or something, not sure...)
Anyways good luck! Thanks for not giving up!
