Walk the Plank Hard one but a really good one to start off the rank. One of my favorites!

I've seen a picture of this level from a group DM on Discord, and I believe there wasn't any steel there, and so the solution I had in mind for it just by looking at it by going underneath all the traps wouldn't work here. That's really good with using a digger in combination with a builder staircase on the left side of the pit to contain the crowd, as well as to get low enough in order to bash to the very big wall. In the meantime, a climber worker goes on ahead to mine to get down safely and build over all the traps. Well done mobius!

90 MPH down a dead end street Quick solve here. The main difficulty is the tight time limit, though I could had made it far less tight on time by blocking earlier. I like how you need to get two worker lemmings in different parts of the level to prepare the route, one to bash through the OWW, the other to patch up the gap at the bottom with a builder.

Cold Irons Bound I think I remember this one from Lemmini. I struggled more than I thought I would here. The hardest part was getting two worker lemmings to go on ahead to prepare the route, though the first one must have enough time to build enough of the staircase to the right past the exit before the other slips by and gets into danger. That was hard to work out. We also have a buried exit trigger here.

Over my Head Two skills and done

I don't think it's supposed to be that easy, so very likely a bad backroute

It Takes Time to Build Great puzzle here with repeatedly digging and bashing, with the bashers our casualties and hence you need to dig to contain everyone before any fall out the basher tunnel into the lava. I did check and it is indeed in the Lemmini version. I do wonder why this needed to change for the NL version, especially since the title is technically not 100% correct anymore due to using platformers instead of builders

Various Positions Repeat of Friendly 19, except this one just uses the classic skills. Essentially the same solution can be used here, except you go over the top with climbers and time one to turn around in the miner tunnel to mine to the left and then build to turn around. There isn't much of a big window here to do so, and so I'm not sure if this tight timing is needed.

Tres Hombres I definitely remember this one, and I think it is in the Heinous rank? I remember struggling here, though I used the basher only as a stall, which is just enough in order to not fall off the builder staircase and to get trapped in the bottom left area. Surely there is a way so this very tight timing isn't needed? Knowing myself, there is.
Brouhaha 8 -
Even you, Brutus Another Patience/From the Boundary line remake, except here there are no bashers. I contained the crowd at the bottom left and other than that pretty much used the same solution as the one from the previous rank, so not that much harder.
Brouhaha 9 -
And then there were three I definitely remember this one, although I don't think there was an ice steam blower trap to prevent the one in the middle from going down to the bottom area? Somewhat hard, but a really good one! The hardest parts IMO was bashing into the steel to turn around, as well as how to keep the lone lemming in the middle safe. Builder placements are crucial here so that he can build to the right later to seal off the gap
Brouhaha 10 -
Presto Chango Easy one, and I one-shot this level. Very good level! I believe this might be in Lemmini, and if it is, obviously no platformer here.
Brouhaha 11 -
Phase Four I think I remember this one from Lemmini too. Somewhat hard, though it should be obvious that one must bash out to the left so that you can get to the upper area of the level where the exit is. Here, I used a blocker along with maxing out the RR to create the right timing to turn the builder to connect with the wall on the right The rest isn't too hard, once you realize how to get the others up to the exit with the climbers since there's nowhere near enough builders to just simply build up with all entrances and that the diggers are the sacrifices.
Brouhaha 12 -
Going Down? Another bad backroute here, as I'm certain it's not supposed to be this easy like Brouhaha 4

This time, it's 3 skills and done.
Brouhaha 13 -
Short Hand Operation Another nice level here. The hardest part was containing everyone in the chamber on the left, as everyone still needs to be able to step out of the digger pit in order to do so. What will affect this is how close to it you dig. Once you're successful there, the rest is easy.
Brouhaha 14 -
Every Which Way But Loose Favorite of mine here!

I think I remember this one from Lemmini. The hardest part to see here was using a miner to turn two lemmings to the left at the start to prepare the route, one to bash the crowd out, the other to patch the gap at the bottom and then build to the exit. Nicely done here!
Brouhaha 15 -
Take A Giant Nose Dive Another excellent level! Quick solve here, especially since it's easy to turn the worker around at the bottom to make the splatform for the crowd. I also just realized you can use part 2's solution here too.
Brouhaha 16 -
Who By Fire? Remake of Lock Up Your Lemmings/All or Nothing. I struggled here, but that's because I kept confusing myself as to how the solution should look. I was a dummy here and didn't realize that one doesn't need to send a climber from the pit out to the left. Instead, two climbers go out to the right, and the one that gets trapped will later get a climber to bash to the left to release the crowd but timed in such a way so that those who spill out to the left after the digger connects with the basher tunnel will turn back to the right towards the exit. Then he alone collects the builder pickup and builds to turn back towards the exit. Nice puzzle!
Brouhaha 17 -
Death Trap This is essentially a repeat of Flapdoodle 22 but in zanzindorf's Kiwi tileset. Somewhat harder due to only no miners, but it's just timing a climber to get in the digger pit and bashing to the right, building to turn around, then digging to get low enough to bash the crowd free.
Brouhaha 18 -
The Prestige Hard one but another really good one. The far left area was quite enticing, especially the bottom, but turns out it's a red herring. Instead, the top of that part of the level is used. Getting the timing can be hard here in order to seal off the tiny gap to the right after all of the bottom entrance climbs up past it before they get blocked by the builder staircase and can't escape. Figuring out the route for the entrances is certainly not easy.
Brouhaha 19 -
The Lemming with the Golden Gun This one wasn't as bad as I thought, though I do use the trick of bombing a lemming trapped between two blockers to release them both twice. I forgot the zapper trap isn't too fast triggering, and so you can still have lemmings not that tightly compressed and they'll still be able to slap by the trap without getting killed before getting triggered again.
Brouhaha 20 -
Push the Button, Max A surprisingly deceptively difficult one despite just two skill types. The main challenge here is making sure that no one besides the diggers to get to the buttons also gets trapped with them.
Brouhaha 21 -
Last Lemming Standing Another deceptively difficult level. This reminds me of another custom level where it was wondered if the current version is impossible on Lemmix because of how climbers are able to get past the wooden staircase. Now I'm trying to find the level again and trying the solution I found here to see if it's possible on it. I'm not sure what the gliders are for, as I didn't use them.
Brouhaha 22 -
Lemmings in Arms I definitely remember this one. Not a hard level, only due to the time limit. It totally escaped me to patch up the small gap at the bottom so that everyone from the bottom entrance can float down safely in order to save and finish on time. It would appear that all lemmings from one entrance get climbers, while all lemmings from the other get floaters, but it's necessary to get at least one athlete past the big OWW. You can either block to turn the other one around to bash through it, or you can use the digger in combination with two builders to turn around if you're aware of it. Either way should work, but if using the latter then you just bomb the upper entrance free instead.
Brouhaha 23 -
The Midas Touch I also remember this one from Lemmini. Somewhat hard, although it's probably because I used the harder solution, which actually turns out to be the intended solution if going for the talisman. Here, the digger has to be placed very precisely, and you have to cancel the first miner with another miner at the right spot. The builder is also precise. Otherwise, there's a much easier solution which completely escaped me. I think I even remember solving it this way. What the lapse of time can do to the player

Brouhaha 24 -
Five for Fighting Yet another I remember from Lemmini. Nice trick of sending two on ahead while everyone else gets contained in the pit at the top left, where you need to mine so that you can release them with a builder later. This can be hard to see. I also like turning the second climber around in the basher tunnel to build a landing platform for the others.
Brouhaha 25 -
Constructus Interruptus Nothing special here other than it's primarily a builders level. Here, the builder wall is used twice, one on each side, to contain the crowd at the top. The rest is just figuring out how to build in order to get the crowd down safely, as well as still be able to access the exit.
Brouhaha 26 -
Jacob's Ladder I also remember this from Lemmni, though that version is backroutable and unfixable. This reminds me of the Clammings level with the blockers and bashing to free them later. I thought to release them all at the same time, but turns out you start with top ones and slowly release the others as the right opportunity allows so no one else gets into danger other than the bashers going to the right, who need swimmers.
Brouhaha 27 -
Sneaky Pete Hard one, though it's because I kept thinking about the level's solution the wrong way. It was very hard to see that the route is out the right side instead of getting up to the exit from the left side. Also you would think to get everyone to the bottom, but this doesn't work. I wasn't sure whether it's intended to use a shimmier to delay him, but after checking your replay it is indeed intentional. I kept thinking that one builder would be enough to get to the exit, but turns out it doesn't work. Nice level here!
Brouhaha 28 -
Resistance is Futile Another hard one, but I generally struggle with zombie levels anyway. My solution is kind of complicated in that the blocker needs to be placed at a specific spot, as well as the miner being very pixel precise so that he releases the blocker but also gets interrupted after a stroke and create a pit deep enough to turn both climbers around. I checked your solution, and yours is just as hard, since it uses compression and very good timing in order for all to exit just before the zombie barely comes back on time to infect any. I think lemmings are safe from infection once they start the exit animation. I'm not certain.
