Thank you. Being able to reduce the number of walls was completely unexpected, but I’ve decided not to fix it.
How did you do that?
I created a prototype with extra space at the bottom right to confirm that a solution existed, and then looked for ways to reduce that space.
What you need to do at Level 3 is the same as what you need to do at Levels 12 and 16. Level 2 is also almost the same, but Level 3 is primarily designed to explain the differences from Level 2.
