D game engine -- Any suggestions?

[Mineko]

Yo, I'm starting off a new game engine designed around D, and I 
just wanted to know if some of you might be kind enough to review 
some of my base code and tell me if I need to change anything in 
it.. While it's small. ;_;

I'm still learning D, I quite like it, the power of C++ in some 
parts, and the ease of Java in others. (Good job Walter!)

Anyway here, check it out, only ones you really need to pay 
attention to are main.d, time.d, and input.d.

Thanks for helping out a newbie, and if you want to contribute to 
it, even better!
