The first Lemming from the the left entrance should be the climber AND the one you bomb instead, when he has fallen back down, therefore allowing the second Lemming from that entrance through instead of falling to the bottom like the others

Tough 1 - The Flagpole and the Box Great level to start the rank. Not too hard of a level, though the hardest part here was getting a Lemming to turn around at the very end of the basher tunnel in order to dig so that he gets low enough to mine the bottom entrance out. Thankfully, the player can better get this via the RR.

Tough 2 - Rope Swing Looks daunting and difficult, but it's not too bad despite appearances. Once you realize the way to keep the second Lemming safe is to have him dig all the way down at the start and then you can release him from the pit with the climber skill, then the rest of the solution should come easily. It might still be difficult to find the best way through the ropes, though. You're pretty much given exactly the bare minimum of what you need to solve the level, so you can't waste any builders whatsoever.

Tough 3 - Catacombs Pretty much a breather level for the most part, especially as it's quite obvious that you can't go through the bottom entirely and that you must go over the top. This is pretty much the hard part, knowing where to build to get everyone up. I finish the level with a lot of miners to spare, so I don't know what those others are for. Even then, there doesn't seem to be any harm in keeping them in, especially as I don't see how the level can be cheesed with them

Tough 4 - No Justice Quite possibly the hardest level in the entire rank TBH. For the most part, I kept wondering if the level is even solvable with the given skillset, as it always looks as if you're a digging destructive skill short. In the end, after a long struggle, the solution I found requires a lot of pixel precision, particularly the second climber to stop the first one who digs, as well as a very precise bomber to get the left entrance out and into the miner tunnel from the first climber. If this is intended, then I suggest heavily reducing the precision needed and/or eliminating it. Levels that require a lot of pixel precise skill assignments in the solution aren't good design IMO. It's one of those things that just because you can doesn't mean you should. At least when I test my levels, if too much precision is needed, then I like to help the player out by either reducing it or just outright eliminating it. I don't like players failing my levels because of pixels. I want them to fail because of the puzzle!

Tough 5 - Jenga Another hard level IMO. A lot of my attempts failed because I couldn't find a way to keep the neutrals safe while one of the regular Lemmings builds to get to the exit. Turns out I simply needed to realize to use a builder to make a splatform first before building to the exit. I don't think there's really a way to delay the neutrals further, at least without them climbing into danger later on as a result, such as into a bear trap or falling into the acid.

Tough 6 - Iron Gate Nice level even though this isn't the intended way that you need to do the final level for this particular mini-level! Isolating the first two Lemmings from the rest of the crowd while one of the two pioneers bombs through the OWW and then builds across the gap and also over the ketchup wheel trap and then the crowd can release themselves by bashing. It's still a much faster solve than either of the two previous levels, so it's definitely much easier than them.

Tough 7 - Crystal Clear? Quite possibly the easiest level in the entire rank because this level literally took me no time at all to get solved, and so yes, I would agree that the level is indeed "crystal clear"

Tough 8 - One Minute, One Of Each Skill Nice level and a tad bit harder than the previous one, with probably the hardest and trickiest part being just a bit before the exit. I don't know if my solution is intended though. It's always nice to see a level made with Gronkling's Menacing tileset. I'll be honest, and that is I was amazed at this special graphics level of L1 as a kid, rather than freaked out by the blood and strains. Good music as well.

Tough 9 - Z Cave Another easy one, as it's obvious that the miner needs to bounce off two blockers. The only hard part here is preventing the other entrances from dying to the deadly sides.

Tough 10 - Pair of Aces I love the design of the level here which is meant to depict playing cards. In this case, Ace of Spades and Ace of Diamonds. Hard level here, as even with a lot of builders available it's not easy to determine the best route through the playing cards, especially the latter. I must say, that hidden steel in the middle is pretty evil. I think you may be aware as well, but deceiving players like that tends to be a big no-no in the NL community. Most players agree that all information to solve the level should be visible from the get-go and not hidden. Of course, if one wants to during play, CPM can be activated ahead of time to know that the middle part is steel and not destructible terrain like I thought it was. So, I brought that on myself, but in general I usually don't use CPM in my live LPs Overall, nice challenging level!

Tough 11 - Spectacular Pretty much the best level of the entire rank IMO! The hardest to see in the solution is the user of the bomber, but that realization didn't take too long for me as I kept trying to fiddle around with not using too many builders to build across the gap at the bottom. Certainly the hardest part afterwards was releasing the top entrances while making sure to have enough builders to do so and to get up the miner tunnels, though that would leave you a builder short if you do the latter. The alternative, then, is to get the middle entrance down by having them mine out so that they will come back up the side of the level to reach the exit. I really enjoyed figuring out this level. Well done, though I have a builder to spare

Tough 12 - Wind Tunnel Ah, so the level from the Easy rank does get repeated here, which we all thought you meant to have the player solve via compression through the traps. Nah, this is the level, the repeat, that players do it on, so I guess that renders what we said about the level in the Easy rank moot That's certainly not the hardest part but rather how to achieve the compression and then be able to release everyone to go towards the traps at the end, except for the worker who did the bridges.

Tough 13 - Desert Island Night Rescue Team Pretty much a breather as well, as it's the rare level where one can simply use the standard two blocker trap to hold back the crowd while one Lemming goes on ahead to make the route for them. Also, as long as you realize that you can only save 3 of the 2-neutral groups, then this level isn't a problem in any way. I did think that maybe the intention is to make bridges that span across so that you can free all the neutrals with one of the bashers, but thankfully that's not required, as you are allowed to lose both the blockers and two of the neturals which can't be freed.

Tough 14 - Multi-tasking Looks daunting and hard but it's not that bad at all. Pretty much the only hard part is making the splatform to save the right entrance, but you do have plenty of floaters to spare so luckily it's not too tight. Perhaps keeping the left entrance safe is the harder part of the level. I do have plenty of skills to spare, but maybe it's supposed to be an open-ended level. Decent and somewhat challenging level here.

Tough 15 - Crosses and Noughts Sorry, not a fan of this level at all! Way too many repeated bomber and builder assignments make this really boring and not fun to play. Sure, it's a breather, considering the lenient save requirement and all, but didn't find this fun in any way.

Tough 16 - The Sands of Time Also a breather IMO, with probably the only hard part is to have one Lemming turn around after going down a level so that he can prepare the rest of the way for the others before too many get into danger due to turning around. I used the final 3 builders to turn the 3 back towards the exit while the basher was still going. Not sure if this is intended.

Tough 17 - Derelict Staircase Looks difficult, and indeed it does seem to be the case, especially if the intended solution is enforced. This seems to be a backroute I found. I'm not sure if digging to avoid the trap is intended here. I expected them to get killed on the other side if doing that, but apparently there's a wall there that prevents them from reaching the other side.

Tough 18 - Cave Explorer Sorry, not a fan of this level either. It's quite obvious what you need to do here, but way too much bridge building for my liking. This does remind me of an L2 Outdoor level that has something very similar, though I can't remember if you're given anything else other than just builders and diggers. This level does seem to be inspired by that.

Tough 19 - The Chains That Bind Nice challenging level! Don't be fooled by what seems like a lot of builders and miners. At least in my solution, I ended up using all of them. Certainly not easy to find the correct route through the level while making your way to release the neutrals. The 99RR makes the start difficult, though because the start is all steel and you don't have bombers, then it's clear that to release the crowd later on you need to block on a built staircase to release both the blocker and crowd later on. I kind of enjoyed this level, though some parts were a bit fiddly to do, especially when building and then mining while not turning around and/or the staircase gets chipped off so that the Lemmings will slip through from the other side.

Tough 20 - The Arches Still seems to be a backroute here, so looks like it needs further fixing still I'm guessing the titular arches are used in the intended way as indicated by the level title.

Tough 21 - Oh Balls! Another excellent level and definitely far harder than the original in the Easy rank. I especially love the extending the basher part of the solution, though I would say it's probably also the hardest to see in the solution. Well done, and the time attack talisman is certainly not hard to obtain at all, especially as long as you bash at pretty much the first opportunity you get, before the builder gets put in place for it to keep going

Tough 22 - Looks Simple..... This one also seems to be a bit inspired by an L2 level, this time in the Classic Pillar set. I think it was called "Mr. Lemmy Doesn't Live Here Anymore" or something like that. Kind of a breather, though probably the hardest part is figuring out how to get someone to come back to the crowd to mine the crowd free. Here, it seems climber bombing is the most logical choice to get through after building across the gap, but bashing it away instead occurred to me a bit later. It's a bit unfortunate that the climber who mines the crowd out isn't able to reach the exit on time, but oh well, sometimes that's the way it goes

Tough 23 - NuMaCaBaBaB I'm guessing that's a lyric to a song or possibly even the name of a song? Pretty much a remake of "Now use miners and climbers"/No added colours or lemmings," just with two steel walls instead. The solution is pretty much what you expect it to be, with probably the only hard part is building over the gap before anyone arrives and falls in and is trapped there. Nice level nevertheless.

Tough 24 - Crocodilopolis Wow, excellent level here! I really enjoyed solving this one. One of the hardest levels of the rank for sure but one which feels to be the right difficulty. I think the solutions can easily swap sides here. Got the gist of the solution fairly quick, though took me a while to figure out to dig and then the next Lemming from one entrance builds to be delayed so that the other Lemmings who spawn from it can survive the fall into the pit. I really love how there's the mining through the bridge to release the ones trapped in the pit by climbing solution element of "no added colours or lemmings" level here. Well done!

Tough 25 - Fort William Somewhat of a breather this late in the game. Not really hard in any way, especially with plenty of climbers to keep the bottom entrance safe. It can be a bit chaotic keeping track of everything. Probably the only hard part is getting the bottom entrance up, similar to Tough 3. Otherwise, nice level which I kind of enjoyed playing and solving

Tough 26 - One Floater, One Climber, keep moving... Looks to be quite daunting and challenging, though my solution is probably a slight backroute. The solution does seem to get the three move involved in cooperating with one another so that one of them keeps the other two safe throughout the entire level. This level kind of reminds me of a level from Lemmings Reunion, which I believe is called "Den of evil" or something like that. Similar concept, where one is a floater, another a climber, and the other one is neither one and just a regular Lemming.

Tough 27 - Clam Dune Probably a bit harder than the previous level, especially with the 99RR and multiple entrances to deal with. A few skills I spared so maybe a backroute as well? I love all the clams you put on the sandy dune! Very nice background which goes really well with the L2 graphic set.

Tough 28 - The Red Room This level doesn't too difficult at first glance but there's still some gotchas to watch out for. I think the hardest part for me here was figuring out how to get two Lemmings to go on ahead, one of which bashes the final wall while the other one turns around to build the splatform. I'm not sure if the spot where I built in the solution is required so that if you bash at the right spot then the crowd doesn't get released. If that is intended, then that's certainly the hardest thing to spot in the solution! Very nice! Probably about the same difficulty as the previous two levels.

Tough 29 - It Burns! Sorry, another one I wasn't a fan of. Way too much repeated building and blocking on the left side to reach the exit and is way too fiddly to execute. Granted, there might had been some things I could had done to make it a bit easier, but for the most part it's really annoying to do. Quite possibly the worst level of the pack IMO. Probably the biggest improvement might be to leave more wiggle room with the flamethrowers on the building up side. This level does seem to be inspired by I believe it's called "Blood Furnace" by Crane, only this one has a bit more than that.

Tough 30 - The Last Level: A trip down memory lane I like how this is 5 levels rolled in one where you essentially just repeat the solutions to them for the most part! Now I definitely know I didn't do the Brick level the intended way. Pretty much the Bubble and L2 CaveLem levels both have a slight modification to the solution from the originals. My failures came about due to doing them incorrectly and sub-optimally at first. I think the rest of the solution came easily once I realized why the great number of losses you're allowed which will come in the Bubble level. It's not easy to see how to release the neutrals in it while not using too many builders. I think luckily needing to climb back up to the neutrals to release the blocker in the L2 CaveLem level came quickly as I got close to getting the level solved, as you really don't have any other options with the skills you have left for it, if you did the other mini-levels correctly. A great level to finish off the pack on for which the AWESOME music track plays! I believe Lemmings Rundown by LemFan does this as well, with the AWESOME music track also playing on the final level.
