Let me ask you, the first level in the game, are you supposed to jump over the DTs, or are they supposed to be an actual wall? If you want to restrict lings from going past there, put a better wall up.
But anyway, there are no indirect clues into leading me to what to do. We tried putting 2 and 1 ling across the wall. There aren't any clues. Oh, and go head and ignore Kupo.. he just wants minerals/posts
