Hi all, I have a new puzzle for you. It’s a light switch problem again, but this time you have to walk on a grid, with a predictable result at each step. Kudos to @will @E_RedMark for the feedback. @will, you can now play the same board again to improve your score - the map will show you the minimal path.
@Charles_Parkes This also uses the keyboard, let me know if you have suggestions on the interactivity.
