Soft 04, "This time": The talisman now requires you to only use 3 Miners, not 4. Sorry to everyone who had attained it already, but that was indeed pretty much... everyone. In diagnostics of cognitive performance, we call this a "ceiling effect". If everyone can attain a talisman easily, it doesn't really mean anything. Thanks to Gronkling for finding this new solution! (And also, I didn't want two talismans on the same level, especially not on such a simple one, where the difference between bronze and silver would literally just have been 1 more instance of the same skill.)

Soft 23, "Don't worry, be happy": The fire pit has been made slightly higher. The talisman is still attainable, this solution isn't impacted by this.

01: Better than the intended solution; slightly worse than the talisman solution, though, because you needed the Floater.
02: Intended.
03: Intended.
04: Oh wow, this is the first solution I see using only 3 Miners! Maybe I should make that the talisman requirement? Since solving it with 4 of 5 Miners seems to be something literally everyone is capable of.
05: A lot more skill-efficient than intended.
06: Intended.
07: Intended.
08: Intended.
09: You're the first one who used the Stackers on the left with the Climber, which is part of the intended solution. The rest you did completely differently, but that's absolutely fine! It's amazing how many different, yet equally difficult solutions this level seems to have!
10: Intended.
11: Intended.
12: Intended.
13: Intended.
14: Slightly more skill-efficient than intended.
15: Intended.
16: Intended.
17: Valid alternative solution! This one was rife with backroutes initially, so I'm glad to see you had to use all but one skill.
18: Efficient alternative solution.
19: Intended. You just "split up the Platformers" by platforming partly high, partly low across the water. I just sealed up the entire pond at the same altitude.
20: Intended.
21: Intended.
22: More efficient than intended. You didn't need the Blocker to cancel the Digger, because you dug in just the right place to still leave 1 pixel behind that broke the fall. Also, no second worker lemming (Climber) required to platform from the exit to the Miner tunnel from the left. Still, I leave those skills in here, because other people clearly needed them for their solution. It's still the first rank, after all.
23: That's the only minor backroute. One of my testers already platformed over that fire area, but then had to use so many of the other skills elsewhere that I was fine with it as an alternative solution. This one however saves a few too many skills for my liking, so I can no longer allow that shortcut. Thus, as a side effect, one of my tester's earlier solutions broke now. Sorry! I just checked though, the talisman is still attainable.
24: Intended. Funny though that nobody fences from the right after the pioneer lemming is done building. I could enforce this with one-way arrows, but it doesn't really change anything. In fact, one-way arrows sometimes give the solution away more than if they weren't there.
25: Intended. Actually probably even slightly better than intended. I'm pretty sure though that the last Stacker wouldn't even have been necessary. This is because you used two stacks on top of each other to pen in the crowd, instead of using that pole of three red squares. If you do the latter, you need the additional Stacker to prevent any Climbers from getting trapped between the "containment stack" and the "release-the-crowd-again" stack.
26: Yay, climbing through corners! A good trick to know, might be come relevant on later levels. Here this allowed you a slightly more efficient solution.
27: Intended.
28: Intended.
29: And here's another open-ended one with countless equally fascinating solutions. You're the first one I see who solved this level from the right side.
30: Slightly more efficient than intended. You saved 2 Platformers, despite building up all the way to the chain on the left, instead of using another Stoner to turn around there.

11: A slight variation on the intended solution: You bashed the Stoner away again after having used the Stacker to prevent the crowd from walking into the water once the Stoner was removed. The intended solution uses the Stacker to build over the Stoner from the right, so that it never actually has to be removed.
12: This is the more efficient version of the intended solution: Stoning on the left instead of the right side of the gap saves two Shimmiers.
13: Intended.
14: Similar to Gronkling's solution, a little more efficient than intended. Don't know what that last Climber was for that went straight to the exit, though .
15: Also pretty much intended. You can platform from either side, but you definitely need the Shimmier to mine, because the Climber is needed to get back up the pillar after collecting the Basher pickups. And enforcing the Shimmier going along the bottom side of the Platformer bridge is what this level is all about.

QuoteStormy 19, Rickafinity - I think this might be the fastest solve we have so far on this level.

You mean in terms of time remaining? It's not like there was an awful lot left of it in my solution either. I thought it was just to provide some leeway. Has everyone else literally solved this at the very last second?

QuoteMurder 1, The Five Arches - I have never seen a Blocker do that before....

Wait... are you talking about stopping a Basher with a Blocker? Are you serious? You were the one who showed that trick to me, on your LP of Lemmings Migration!

Soft rank: Raindrops keep falling on my head
Loud rank: November rain; Red rain; In the bleak midwinter (snow)
Heavy rank: A change of seasons (both rain and snow)
Hardcore rank: Hammer-smashed face; Wipe your ass with sandpaper

In fact I'm pretty sure you had to stone beneath the receiver, or platform along there - anyway, at least one worker lemming had to go through it.

Soft 09: Completely different than intended, but perfectly fine! This is basically an open-ended level where the iffy terrain shape and the lethal drop for the central hatch are the main challenges, no matter how you overcome them.

Soft 10: That's a nifty little trick you used there! I think Armani did something similar with the Glider, showing me that Reacher-Glider tricks still work (especially with updrafts) even after the physics change. You however didn't even need the Glider, because you instead exploited the fact that Reachers can jump through small stripes of terrain. I think WillLem was the first one to demonstrate this to me. This isn't actually required on any of the levels in this pack (I did make a level for my upcoming pack Lemmings: Hall of Fame, though, where it is indeed relevant ). I guess this means that while standing on top of the Stoner, the lemming was actually already under the wooden stripe of terrain. If you had used the Glider, you could even have done it a couple of pixels earlier, i.e. before the lemming was under the stripe of terrain.
Neither trick is required to solve this level, though; you can also just use the Glider and all the Shimmiers for their normal applications.

Soft 11: This is the first time I see an alternative solution for this one! The intended way is to widen the Fencer tunnel with a Basher going down the slope, so that the Shimmier can continue all the way to the pillar on the left. You instead used the Stoner to isolate him while disarming the traps and saved the Basher for cutting through the Stoner later on. I don't think there would be a way for me to prevent this, even if I wanted to. But I'm actually fine with such alternative solutions, especially if they still use all the skills. Sometimes it can come back to hurt a player later though, if they miss an opportunity to learn a certain trick (in this case: widening a Fencer tunnel wish a Basher so that Shimmiers can pass through) that may be required again later on...

Soft 01 - Intended (Talisman).Yeah, that left side looks a little "loose". It's to enforce the Floater usage, but of course, the talisman solution doesn't require it.

Soft 02 - Intended. I am very confident this level is harder for the average player than the first one, simply because that Stacker-Stoner trick is still not that well-known yet. And here there is literally no other way of freeing the crowd at the end.

Soft 03 - Intended. Don't overlook one thing: This level is the first to introduce direct Climber-Shimmier transitions. I actually added the Shimmier to level 02 to get one regular application out of it first, i.e. where the ceiling is low enough so that the Reacher can get to the ceiling on his own. Because if level 03 was the first time a player encountered the Shimmier, they might think it was just a "vertical Jumper", or even that "Reacher" was the actual skill name. For any player who wasn't already here during the discussions leading up to the introduction of the Shimmier, it may not be obvious at all that Climbers can transition into Shimmiers directly. Especially because NeoLemmix doesn't use the "dangling from the ceiling" animation, as Lemmings 2: The Tribes does.

Soft 04 - Intended (Talisman). Well, I for one had quite a lot of trouble getting used to this logic of "using Miner tunnels to turn around while they are being created", so maybe I overestimate the difficulty of such puzzles . It's mainly in spot 04 though as an homage to "Now use Miners and Climbers" .

Soft 05 - Valid alternative solution. Glad to hear you found this one a little trickier, because it was backrouted countless times during testing .

Soft 06 - Intended. Using Shimmiers + Gliders to turn a lemming around is indeed the new thing that's supposed to be taught here. The trick was even less obvious before you implemented the physics change Because that bar on the left could still look like all the other ones back then. After the physics change, in order to give the Glider sufficient height again to bump into the wall and turn around, I had to do this weird carved-out part that you see now, which gives away a little more that you need to do something special there.

Soft 07 - Intended. Yes, it's probably what "Glide and joy" was in Lemmings World Tour. A potential early roadblock. It's in position 07, again, as an homage to "Builders will help you here".

Soft 08 - Intended. Thanks, you were the first one to use the Glider solution!

Soft 09 - Very close to intended. You managed to pull it off without the Miner.

Soft 10 - Intended. Yes, I remember from your feedback to the Groupie level I had made in your style for Lemmings World Tour that the extent to which one-way arrows cover chunks of terrain is one of your signature concerns. In this case, it would bother me if not the entire height of the pillar was covered; but it's just one pixel-width on the left and right side each, which actually makes it look quite symmetrical to me.

...using them for a bunch of other purposes than crowd control, and usually in a manner where they can be freed again.

In contrast, a lot of players only practice Blocker usage at the very beginning of their journey, until they encounter levels that require more advanced forms of crowd control (Digger pits, sealing off Basher tunnels with Builders, three-Builder wall, etc.).

The downside of that however is that many of us no longer use the Blocker very much at all. If you're one of the players where this is true (as it is for me), this will DEFINITELY come back to bite you when you first attempt SEB Lems.

Hopeless Fantasies: I didn't realise I had to do a "2 for the price of 1" approach and bomb a lemming that otherwise would have drowned anyway.

Mean Green Machine: Cutting that one Basher in comparison to Arty's solution (which you didn't call a backroute in the comments! ) really made this level unnecessarily precise timing-wise. I had to re-assign the Digger on the left repeatedly to get him in the narrow time frame of "passing the exit while still closed" and "not reaching the abyss before it's been sealed up by Platformers". While looking at Arty's solution I thought "Why didn't this occur to me? Did I just overlook one Basher, or did I waste it somewhere?" No - it actually wasn't there anymore.
Also, the Old-Formats version featured anti-splat pads instead of updrafts. Thought about re-adding those?
For a while, the updrafts confused me even more, because they made me think the whole crowd should travel down with the Digger. With updrafts resetting fall height, this is technically possible (if it weren't for that force field, even if you block after the first drop). With anti-splat pads, it's clear this path isn't an option, because you would be digging away the terrain inside their trigger area, and the lemmings would splat again underneath.

Thought of Jigsaw and made this: I had the Stacker trick and everything figured out, but didn't see a way to make all Climbers survive until they reach the left side. Because I didn't see a way not to make the Glider a Climber as well. So I had to watch just the very beginning of IchoTolot's solution (since Arty's was a backroute) to get the crowd containment right. I never would have thought there would be enough time to let the Glider mine first!

Wild Forever: I traditionally suck at compression method. I was aware that you can use Bashers and Fencers to compress lemmings by having them "walk up on each other". But I hadn't thought of doing the same with Floaters yet. That a Miner has to go through, this was clear to me right away, since I like to use that a bunch as well. And the green grass parts thankfully facilitate proper placement of everything, including the Digger at the end. After that, I also went back to solve "Scarborough Sands", which I had skipped earlier, but I didn't actually have to look for any hints here. Just the context of having done "Wild Forever" first was enough. But that's why the replay file for Stormy 05 has a later "last-modified" date than the rest.

06: Intended.

07: I was curious when I heard you used a timing-based solution. You still built to the left before you built up for the second part. However, you actually re-connected the crowd with the first section and had them walk back and forth. The intended solution is to only build to the left until you're under the pillar, so that the crowd keeps walking to the left, then have the last lemming who comes in from the left (i.e. is still looking to the right while falling) land on top of the staircase and build up from there. No lemming from the crowd will be able to follow him because they all continue walking to the left, until you have the crowd build up to the staircase again from the left (=looking to the right) after the water gap has been crossed. Learned this trick ages ago from mobius, tried to enforce it on his Groupie level in Lemmings World Tour, didn't work - but here it's vital!
However, the fact that I now know there is a timing-based alternative means this level has more degrees of freedom. Therefore, I feel it's all the more justified to be on the first rank.
Yes, the level is a step up in difficulty, but even this one doesn't actually enforce the "mobius trick" as strictly as I thought it would .

08: That's basically intended. I just find it curious that nobody seems to want to use the Glider . When you set up the second staircase with a lemming from the left/upper crowd (=letting one slip past the Blocker, making him a Glider, then cloning the Glider before he falls so that the clone still turns around on the Blocker, then both glide down, you stone the first one so that the second one lands on top of the Stoner), it should be easier. Because the Stoner should be in the exact right spot where the second Builder needs to go. On the other hand, sending all worker lemmings from the right means you don't have to divide your attention as much between the two crowds.

Regarding the precision: Yes, making Miners go through is always precise, but believe me... I have both played and designed much worse "Miner marathons"...

Do you know the level "Dolly Dimple" from Oh No! More Lemmings (Crazy rank, level 02)? If not, you should probably try and beat that level first.

Alternatively, there's a level in Lemmings World Tour (Noisemaker rank, level 11) called "Can't stop this thing we started". This level teaches the exact same approach as "Dolly Dimple".

This is what I meant by "You need to know the tricks from Lemmings World Tour to beat this pack". That wasn't a joke!

Hint if you've already beaten "Dolly Dimple" and "Can't stop this thing we started"

You can use Builders to force lemmings to walk into one direction only. The same logic applies here.
Except that in this case, it's not about making them all look in the same direction when falling through a Digger hole... but you still want the entire crowd to look in one direction, the pioneer in the other one.

If you build across the first pillar from the top of the three-Builder wall, there is obviously no way for the crowd to get over that pillar - because you don't want them to get back behind the three-Builder wall, and they can't, even if you wanted them to.

So the three Builders that create the wall on the left and the Builders that get you over the first pillar need to be separate.

How you isolate the worker lemming for the second part of the level... that is a different story after that .
