I think your engine is very interesting! I'm myself working on a game framework for D (with some kind of engine built in). Would it be okey to port your code to my framework? It's been a while since I pushed to my public repo but you can maybe get an idea what I'm working on: https://github.com/Manipulator/New-World-Framework
Go right ahead! Some of my own code (especially in the collision detection department) is based to some degree on others', so I guess it's my turn to share. If you run into anything that could be made better or given better documentation, let me know. Of course, I don't think that much of anything is documented right now...
