Had to fiddle a little bit around, but then got the hang of it. The screenshot helps ;-)
The game once crashed, I think when I created a very short chain, because I hadn't understood, that you have to hold an drag to determine the length.
Yeah I didn't have the time to make in-game directions, unfortunately--I just had to leave people to hopefully figure it out. :p
Weird that it crashed making a short chain. I haven't seen that happen, but the code is spaghetti enough that anything's possible. haha
Glad you got it working!
