Well, welcome back then, although we probably don't know each other yet
!
My brother spent a lot of time on Lemmings Revolution. As far as I remember, at least one level required a patch to be solveable at all, and another one used the bomber-as-a-floater trick to survive a fall (making a lemming a bomber so that it oh-nos in the moment of hitting the ground, then assigning a builder to it to prevent it from actually exploding). I believe that was only possible in Lemmings Revolution.
I did enjoy the concept of Water- and Acid Lemmings - although from a NeoLemmix perspective, they hardly differ from the swimmer mechanically, except that they can block / build / bash while walking on their respective preferred liquid. The most interesting tool to be considered from Lemmings Revolution, aside from the often discussed wraparound feature, would probably be the gravity inverter. In my book, this offers a lot more design potential than the magno booter from Lemmings 2, because those lemmings can still perform skills while upside down!
