This was a tricky World Record to regain! I made a mistake in my previous record by making the Lemmings walk all the way to the left, obviously (in hindsight) wasting time... NHC, who beat this time, improved on that, but his run was less optimal otherwise. This is a tough one to optimise, though, because if you assign blockers too early, the Lemmings will simply walk through them. I got the extra second here, though!
