Loss of Lemmings: Zero
Flame Throw left to get out of the initial pit. Break into the next chamber by using Mortar x3 from under the right hand edge of the initial pit. Start a Runner, and use it to Glue the gap over the pit near the right hand side. Glue again. Blow through to the exit by firing a Bazooka twice, using a Lemming standing about halfway across the glue.
