XNA Game Engine needs help

Over a couple months I have been crafting a Shader based Game Engine using XNA. I tried to find a descent XNA Game Engine and found only testing projects. Torque has a XNA based engine, but for 2D games.

Therefore I decided to write my own. Now I need help, as the base Egine is complete and we need to expand it with more advanced features.

If you are an Experienced Engine Coder, using XNA and C#, then we need your help.

Please see the project for more detail
