I actually have been very interested in this one, the big reasons I think most people arent commenting is
1. You 2 keep switching engines (Rabbit, EOF, AGE for inestical)
2. You keep showing just screens of spheres with some type of tech, but never a level, I'd just make a quick level that you have a character walking around in (if you have collision detection yet with ode) to show that you can do something already
3. Most people like stuff they can download and use, since your engine is still early in dev, most people will not really comment, so I'd take that as a reason to PUSH IT, JUST WORK WORK WORK, until its something people can start seriously using
