Maybe you can offload some of this work to the open source community. I would recommend making a git repository, and using a system to track who is doing what. Github is an easy way to do both. Personally, I think I can help with exporting to other platforms, multithreading, base64 binary data, and the animation sequencer.
Viewing post in VectorBoy 2.0 is coming after all, but there's a catch! comments
To be completely honest, I'm incredibly surprised that there are still people who would download and use this software. It was mostly meant as a goof and there's really not much to it to begin with. I still want to say that I'm very grateful for the support this has gotten since I released it. At this point I would rather suggest you extend other LUA game engines like Love2D for instance, they deserve much more attention that Vectorboy, I believe.
