As I said, it’s little bit Geometry tool, and a little bit puzzle game. Throughout development I was conflicted about which was more important. I wanted it to be simple and stripped back enough that you could use this as a go to Compass and Straight edge app, but to make the natural playfulness of geometry to be as visible and as tempting as possible.
In the end I tried to keep the two quite separate. The drawing area is completely free from outside influence, but there is also a “Challenges” box with achievement style goals. Hopefully this shows off the possibilities of construction and encourages people without getting in the way. If you are the type of person who prefers to make their own goals, you are free to ignore it all together.
