Yes, it was made by a Canadian.
The game is simple: click on the falling red maple leaves. Each click on a leaf makes the leaf go away and part of Canada's flag appears in the background. Once you get the entire flag filled in, you get to see the win sequence. The less time you take to do this, the higher your score. No idea why the score has lots of decimal places nor what the "High : 0" text is.
Tip: Go "click happy" with your mouse, there's no penalty for clicks on the background.
Simple graphics, no sound, Macromedia Flash. Should work fine on any computer that supports flash and can load a webpage in a respectable amount of time.
