No, no, no....
That's not what I meant at all. This puzzle forces you to keep the queen alive. That has nothing to do with efficiency. What I really meant was
"
a puzzle where killing 15 roaches/spawn would be better than killing 30 roaches/spawn"
-not including where the roaches or the queen are needed for something else.
Oh, and thanks for the puzzle idea.
