Back to the original subject, my best level in Lemmings Plus 3 uses a new trick(new to me anyway), involving the use of two diggers and a basher to turn lemmings around.
For example, say you have a structure going diagonally and you need to turn around on it. Dig, have the next lemming turn around then dig, and then make it bash. Block created. ^_^ It's used three times in one level in LP3.
