Too easy. And I didn't see any real scoring, other than an option to submit your score (whcih yu don't see) when you finish. As for having to be quick on the mouse...not really. There is no penalty for getting "hit" with a ball like in the old Windows 95 game. So you can just click and hold your mouse to create a line and then sit and wait until a red ball goes where you want. So there really is no point in this game. No challenge at all.
