Project Lithium Engine is now going into deep freeze. I am the only one doing any development on it, and I've come to realize that doing a generic game engine is very difficult and I don't have the experience to do one myself.

The bad news:
Project Lithium Engine will be dormant for some time. Its in a fairly broken state currently, and that won't change too soon. Lithium Engine may never become a fully featured game engine in and of itself. The new direction will be to create a framework for building an engine inside of.
Sorry for those of you following this project, but definitely keep up with development of the improved Project Helium, which will start posting code in the coming days.
