Can't debug my solution

[Matheus Reis via Digitalmars-d-learn]

Got simpledisplay.d/color.d working by simply adding them to my 
project's folder and I'm now playing with it. What I've 
accomplished so far:

(some objects from a class to draw circles in their position, and 
a simple collision check with screen borders)

I'm pretty satisfied with the results, tbh. :DD

As I said, I really liked the language and will keep trying to 
learn more about it, hoping to make a simple game sooner or later.
