Design constraints:

  • no walls meet at a checkerboard / catty corner angle. All corners are solid L-shapes
  • no 4x4 empty spaces outside of the entrance and nine courtyards
  • no loops where you can return to a point without retracing your original path
  • all small courtyards have an entrance and exit and are part of the solve path to the center
  • all large courtyards (I’m going to put side goals / easter eggs in them) have only one entrance and are reachable as a branch of the solution path after the small courtyard that they are clockwise from.
