If you don't have scripting down, what's the point of the post.
It's like saying, "I'm not good at walking, but I want to be the high-wire act in the circus."
You've got to nail down the basics. Start with small simple scripts like opening doors, changing HUDs etc.
As for feedback....Give up the gravity thing. Trying to float and control several entities just isn't going to happen with this engine. For years people have been asking about it. They post that they're going to work on it, and then we never hear from them again.
