ok, it's a nice idea that we don't need any squares filled in, but, in
increasing order of magnitude:
- time it took to solve the puzzle
- time it took to create the puzzle
- time it took me to find all the right Unicode characters to
make my answer look nice. (I wanted to put a little train
symbol at row 1, col 3, but couldn't find one!) :)
