This turned out to be lot more interesting than I first thought.
We've all seen both kinds of puzzles, but I've never seen them together like this. Turns out the aim is: How to best display the tangle to make the sliding puzzle seem easiest for our brains.
And the sliding game tells you immediately if you did an A or D move, and so we learn ....and become sliding puzzles pros! and I think I finally got rid of my tendency to prefer short paths!
Display: At first it seemed very confusing... then turned out to be very simple. +It looks nice. GJ :)
