Yeah, yours isn't the same solution as mine – there is that slight problem in that I don't quite know how to anticipate the fact that bashers don't always stop when you want them to! I thought that a basher on the second level would only go through the central pillar.
Yeah, it's almost certainly a bug in the basher programming for PC Lemmings (and actually a good number of other ports including Amiga, although I do know the Mac version doesn't have this). The effect of it is that it only checks for "stop if nothing ahead" every other stroke instead of on every stroke. In other words, excepting for steel or falling, you'll find that bashers always stop on an odd number of bash strokes. In your case, it means that if I take care to not completely bash through the thin central pillar during the first bash stroke, I will get 2 more bash strokes, instead of just the 2nd one if the bug wasn't present. Also, the game checks for terrain just slightly beyond the end of what the lemming just bashed, so even though my 3rd stroke didn't actually take out any terrain, the fact that it brought the lemming close enough to more terrain ahead is enough for it to continue bashing.
By the way, did you build a step on the rocky floor there, where there's a yellow dot? You shouldn't have needed to...
Yeah, good catch, that was unnecessary.
Also, other people can feel free to try them - I only seem to be getting replies from cc... I know it's not exactly busy here though, haha!
I know each time I downloaded your stuff the download count was already greater than 1 before I even downloaded, so other people have been trying them out. I think I'm just chattier than most.
[edit: and this time many more replied, in fact while I'm in the middle of writing this!]
Anyway, great puzzle for your new level!
The limited skills and the steel make it pretty clear roughly how the solution would go, but it took a while before I was able to put it all together. Actually, I do have one leftover digger, so I probably didn't quite do it the way you envisioned. I've attached screenshots of my solution in the attached ZIP file.
I also love the way you simulate a lone stranded lemming by an invisible entrance trapdoor, and to have that area off-screen from the initial view so that it looks like the lemming was stranded there all along, rather than seeing it magically come out of thin air.
