I'd love to see an update for 1.1. I was able to make some required changes myself (sound file is now "sounds.lua" instead of "demo-sounds.lua"), but I didn't quite get some others (the new variable leg placement seems to be an issue).
I'm kind of waiting for 1.1 to be released as the main version...
Might look into it before 1.1, but I'm currently dedicating a lot of my time to TextureBase (another mod I've been working on), so no promises.
Thanks for letting me know of these issues nonetheless!
