It's a nice concept. As some others have said if it had some meta-goal or some reason that things had to be connected the way they do, it would incentivize playing. At the moment I sort of felt as though I was playing connect-the-dots, but I was only allowed to connect them using a provided pattern. (I'm the kind of person who liked to draw off the dotted lines in workbooks, creating my own additions to the pictures XD ) Was nice to look at.
Thanks for the experience! ^_^
