The only thing that isn't pen is the points, which I could made it of pen, but I'm lazy. THIS IS NOT A GAME. This is a engine to interconnect points between them and to count the steps of separation between the point and the center by the pythagoras theorem. Is free to reuse in your projects, but you must credit me. If you have any idea for me to do, say it.
100% made by me. Thanks to @Sonsuty_Z for some ideas.
