Neat. By the time I got to level 8, I decided it was time to implement turtle commands, which made the solution to level 8 neater, then advancing to level 9 failed to load the puzzle. Then again... perhaps the js errors on the page are the next level.

  Level 9 loads OK: look closer in the corners!

JS is so meh to write in, why learn it here.
