No, sorry :) there are levels which absolutely require the sacrifice (regular levels and the special ones too)

Your statement directly conflicts with the initial comment that said "but a few years back I found someone had gone through the whole game without losing a lemming on any level"

Who's right? Who got the sources to back themselves up?

I think they are talking about Lemmings while the initial comment was about Lemmings 2?

Ah, that might be, it's unclear to me. Thanks for trying to clarify!

Yes, the subthread is about the first Lemmings
