Oh yeah. Just rules out bombers, then, unless there's some other trick I don't know about.

I think that pretty much every level with bombers available could be solved without one, if you were sufficiently versed in the edge cases of how the game worked. I could be wrong, it’s been decades.

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
