As mentioned previously, the rank already starts off quite difficult with the very first level. I enjoyed almost all of these challenges a lot and I definitely felt most of them were appropriate challenges for me that has allowed me to stay thorougly engaged with the pack and weren't frustrating at all.

LOL 1 - The art of destruction It's not a really hard level by any means, but definitely much more difficult than how most packs start off, especially how you can only lose 1 lemming and so make the wrong skill choice at the start and you'll have lemmings turning back, as well as make it impossible to complete the level.

LOL 2 - Be creative is also another difficult level, although I used exactly what I did with Harmless 3 of Paralems with the stackers.

LOL 3 - Dead Lems tell no tales is the first non-challenging level of the pack where it's possible to have some skills leftover with a lenient save requirement. It then goes back to

LOL 4 - Athletic Aesthetics being another difficult level that requires a lot of thought on which exit each lemming needs to go to. At the same time, I probably made the level harder than necessary on myself. It was a bit frustrating working out the timing. 

LOL 5 - On the fence can be challenging, but only if the player is not aware that fencing into steel causes the lemming to turn around.

LOL 6 - Blocking all over the world is quite challenging, although I might had backrouted the level since I have several skills leftover. I'm not exactly sure what the purpose of the fencer is on this level.

LOL 7 - Candyland climber isn't a difficult level by any means, but the timing of cloning the basher is a bit tricky. Consider making that a little easier. Nothing to say about

LOL 8 - Lemorials other than that it's easier than most of the previous training levels and the solution is simply stone each lemming that comes at the appropriate place.

LOL 9 - I'm going to make you mine requires some thought on which single-use traps to trigger and which ones to avoid, but fortunately there aren't that many choices/possibilities, so it shouldn't take too long to stumble upon the solution.

LOL 10 - Base Jumping Somewhat challenging, but still an excellent puzzle with a nice solution.

LOL 11 - Sadistic choice Good level that's not difficult, but it does require a bit of thought to solve.

LOL 12- All you need is time Too easy, probably the easiest level so far in the rank.

LOL 13 - Annihilation station Back to tricky that requires a lot of thought on how to get the bombers to the appropriate places to get the crowd down safely as well as to the exit. Still, nice level.

LOL 14 - Petrification station The slowfreeze version of LOL 13 and much harder. The main challenge is figuring out how to time and get the stoners to the right places to get the crowd down safely to the exit, as well as how to make the crowd avoid walking into the slowfreeze trap. It is a nice puzzle that I somewhat enjoyed figuring out, but I think I like the radiation level better. The tileset has a downside in that it's very difficult to tell what's a trap.

LOL 15 - Release me Despite being a 2 of everything level, it's quite tricky figuring out how to get to every button. Nice puzzle, though.

LOL 16 - You learn it, you earn it! I have to say that this level is a huge step up in difficulty compared to any of the other previous levels of the rank. At first, I thought the level was impossible because I thought the pillar immediately to the left of the entrance was connected to the ceiling and so there's no way to send the climber. Turns out I forgot the grey border that's shown is the ceiling due to my default zoom level, while the black area below it is empty space that lemmings can walk in. I wonder if the floater pick-up is a decoy and if my solution is intended or not.

LOL 17 - Screwing around Pretty easy, but that's probably because I might had backrouted the level. Then again, this is probably a anyway you want level.

LOL 18 - Ouch, my head! Easy as well. I love the delay tactics needed in this level! Well done

LOL 19 - Apraxia Ah, this is the no skills level you were referring to in the release post. Definitely easier than the corresponding no skills level from the Demented rank of Paralems. I think there might be a range of RR's that can work here. Here, I used a 95 RR.

LOL 20 - Stop right there Excellent level to finish off the rank!

A lot of these were really great puzzles, although some I didn't enjoy as much.
 
ROFL 1 - Honey pie More tricky than difficult, but still somewhat a nice puzzle to start off the rank.

ROFL 2 - That's right Nice puzzle that seems to be a anyway you want level. The first level of the pack to have an excessive amount of skills and to be left with a lot in the end.

ROFL 3 - Step up Somewhat difficult and tricky that still manages to be a bit open-ended. I think the wall height is a bit too punishing, especially since 3 stackers is just barely enough to get them up. In my solution, all the stacks were interrupted at the 6th brick, and the total height was exactly 6 pixels, so one less and both sides wouldn't be able to get up. Also, levels that have an abundance of stackers to get up tend to be the most difficult for me, so this was one of the levels that I didn't enjoy as much as most of the others in the rank.

ROFL 4 - The stock market Nice standard puzzle of isolating a pioneer to forge the path and then release with a fencer.

ROFL 5 - Transporter malfunction Difficult level where all teleporters lead to a bad outcome. This was a bit of an annoying level for me. Not sure if my solution is intended.

ROFL 6 - Basic economics Nice level! Guess I got the timing right so that no lemmings were walking to the left by the time the digger broke through the bottom floor at the top

ROFL 7 - Beware of collectivism Nice tricky level of figuring out how to manage and keep all the different special groups safe: Climbers, floaters, and swimmers. I really enjoyed this one.

ROFL 8 - Doubling down The only very tricky part of this level was the digging and bombing to make a safe drop. Besides that, this can be a tricky and difficult level for most players.

ROFL 9 - The wall (Part III) Picks up again from the two consecutive The wall levels from Paralems. Nice easy level.

ROFL 10 - The long way down Another nice and easy level. The only tricky part is figuring out how to get to the anti-splat pad on the bottom. Luckily, it's just a simple use of a cloner before the last In teleporter. Thanks for making the anti-splat pad inside the wall visible.

ROFL 11 - Wraparound travel I might had backrouted the level. Easy level, though.

ROFL 12 - Lems off the wall Another nice and easy level, although once again repetitive climber skill assignment to 20 lemmings. Not as bad as 40 or more, but still.

ROFL 13 - Let's play Quidditch Ah, a Harry Potter fan I see. I'll be honest, I'm only on the second book. Yup, waste of my childhood. I was never huge on reading. I have seen some of the films, though. I understand the purpose of them being preassigned gliders, as that's how the game is played in the book and the movies. Yet another nice and easy level that's still somewhat open-ended despite the very restricted skillset.

ROFL 14 - Na zdorovje Lem Not sure what the title means. Somewhat tricky level in that it's a bit tricky to isolate a single worker lemming. Nice level, though.

ROFL 15 - Out of the frying pan I do believe there is a level in a Dos level pack with the same title. Nice and easy level!

ROFL 16 - Cannibal cave Somewhat easy level, although the skillset is still quite restricted despite appearing to be leninent.

ROFL 17 - Perpetuum Mobilem Unless this is intended, this seems like a really bad backroute which I solved via compression. Still an easy level, though.

ROFL 18 - Up the garden path A bit trickier than the surrounding levels, but still not that bad. Nice level.

ROFL 19 - Skies and Sand Very nice and somewhat easy level despite the huge size. Once you are successful in isolating the special groups to the right half of the level, the gliders at the top, swimmers at the bottom, the rest is easy. The skillset itself isn't too restricted despite appearing to be so, especially with the ones that you have 5 of.

ROFL 20 - An all new challenge! Nice puzzle that is difficult and hence is quite appropriate for the rank finisher. In my first couple of attempts, I was short of platformers or short of a fencer or stoner, but I was able to figure it out and solve the level  

The levels and puzzles continue to be awesome here!

WTF 1 - The mummy This is like the corresponding Abhorrent 1 level from Paralems, being a zombie introduction level. Nice and easy level to begin the rank once more.

WTF 2 - How to be impractical More tricky than difficult but still somewhat easy. Several concepts here: stoner stepping stone for building, stacker staircase, and stacker/stoner staircase.

WTF 3 - Mountain Rescue Very easy and nice level!

WTF 4 - Check mate Chess fan too? This was quite a tricky level despite being a 15-of-everything level. The most difficult part was making sure that you're not being wasteful with your builders, as they're in quite short supply despite seeming like a lot.

WTF 5 - C(l)on(e) fusion Nice puzzle that requires a bit of thought on the proper sequence to do the level, as well as how to rescue the cloned climber. I wonder if one of the fencers is a decoy.

WTF 6 - Under construction Nice 1-of-everything level! My only critique of the level is how part of the top part of the splitter is hidden from view.

WTF 7 - The overseers Nice puzzle! Once again, compression to get the group tightly together, as well as propr timing, to reduce the risk of infection from the zombies.

WTF 8 - Mission impossible Definitely not impossible and not hard at all, although the lemmings still being able to exit despite the exit trigger area being inside steel is quite amusing. Nice puzzle level once more.

WTF 9 - Another rescue mission Once again too easy just like WTF 3 and not that much different other than cloning a digger and bashing while inside the digger pit.

WTF 10 - Down the drain Another nice and easy level

WTF 11 - Airborne aid More tricky than difficult, with the timing needing to be worked out so that the slowfreeze provides a safe drop for both left hatches. I think I certainly could had made it a bit easier by bombing where the updrafts are, as the place I bombed is nearly splat height.

WTF 12 - I want to believe Another tricky level. Isolating 5 lemmings is not easy to do, but that's pretty much the only tricky thing to do for the level. Once you manage to do that, the rest of the level is easy.

WTF 13 - Arigato, Lemming-san! What a really pretty and nice looking level! Too easy and nice puzzle.

WTF 14 - Connecting the dots Unless you realize that you must take the path through the ceiling terrain, it may look impossible to most players. Nice puzzle!

WTF 15 - Crossing the Nile Somewhat difficult level, considering that this is the first level I've played where swimmers encounter trap trigger areas, which they apparently can't disarm while swimming but can if they're performing a task, like mining or platforming. I think this can throw off a lot of people. It certainly did with me. Then again, I think this illustrates a huge mechincs difference between Old Formats and New Formats. Though, I think there was one United level where a disarmer disarmed a trap while it was building, so maybe there's no inconsistency at all. What is consistent is not being able to disarm while climbing, as I remember there was one United level that I tried that with a climber.

WTF 16 - Not the same but yet as one Now this one was difficult but a very nice puzzle this was! The only tricky part was making sure only two lemmings slip by the first builder.

WTF 17 - We are the Lempions More tricky than difficult but still a really nice puzzle.

WTF 18 - Free-floating tent Nice and easy level that requires the solid ceiling in the solution. I think this is what will throw players off, considering that it's not deadly in Old Formats but is deadly in New Formats. Also, various platforms are inconsistent about whether the ceiling is safe or deadly, so that's another factor too in confusing players.

WTF 19 - Fire extinguisher Ok, I was a bit annoyed with this at first, but it turns out that I simply approached the level wrong. Once I realized that I could make it easier on myself by having a lemming drop and glide from the top, I was able to solve the level more easily. Nice puzzle in that the most tricky part is figuring out how to get across the fire pit gap. Once done, it's an auto solve if you managed to have met or exceeded the save requirement. The fall at the end looks like splat height, but it's not.

WTF 20 - Glueck auf! Nice miner cancelling puzzle to finish off the rank! The timing of sending a climber to circle back to mine the obstacles to release the crowd, as well as to send climbers to cancel the miner, is a bit tricky, but you at least provided a couple of climbers to make it a bit easier.

Not too much to say here as there wasn't too much of a challenge, other than there were some levels that I enjoyed very much while others not so much. Except for Harmless 8, I really loved visiting the levels from the original Fun rank and having to solve them differently with NL skills. In particular, my favorites were Harmless 10 - Dropping Like a Stone and Harmless 11 - Door Stopper. For Harmless 18 - Let's Stone and Clone, it's not exactly the original Fun 18, but of course it's understandable why it has to change because the given skillset will certainly not work with Fun 18. Also, I don't understand why so many cloners are given, although I guess it's to give the cloner skill more of a chance to shine, especially since it hasn't been used to much after Harmless 9 - Orphan Lem. I also liked how you kept the Fun levels that are revisited in their original positions in the Harmless rank. Come to think of it, I believe you did that for all the original levels that were revisited in all the ranks of this pack.

Harmless 2 - Only Gliders Can Survive This, although not that much different from Fun 2, illustrates the difference between gliders and floaters well, especially with the water pond directly below the third column. Well done!

For Harmless 3 - Tailor-made for Stackers, yes, I went for the 100% solution.

Harmless 5 - Splish Splash definitely could had worked better as a swimmer tutorial by removing the obstacles so that the lemmings simply drop into the water and so there wouldn't be anything to bash or dig, but if the purpose was to retain the bashers from Fun 5 in this level, I can understand why, although I believe you also said that sometimes combination of NL skills and the classic skills are needed to solve these revisits of Fun levels.

Harmless 8 - We all turn 'round Hey, sounds like it's close to rhyming with "We All Fall Down." This was the first level that I wasn't a fan of, having to assign at least 95 walkers to individual lemmings facing right. As mentioned before, I thought I wouldn't mind levels like these, but I apparently do, and so I can see why the community doesn't like levels where you have to repeatedly assign the same skill to so many individual lemmings. To be fair, at least the level is very short and over quick.

Harmless 12 - Taming the Beast I don't remember if I ever encountered the hidden trap here, but here I simply used the standard bash through obstacles and disarm the traps as the disarmer came to down without saving those that walk into the traps that haven't been disarmed. I like how you mix traps from different tilesets here.

Harmless 13 - We All rise up Ok, not exactly the same as the original Fun 13 and its repeats, but at least the gap is only two builders high. Honestly, the stats of Fun 13 should had been kept: 20 lemmings and so 20 builders, as well as RR of 1. To be fair, it's not Fun 13 exactly, especially since this solution won't work in the original Fun 13.

Harmless 16 - The Black Widow Ok, first hidden trap I kind of got surprised and laughed, second hidden trap I was like, "again?" If I had been caught again by the third hidden trap, that probably would had been the fastest I would had gotten annoyed, all in the span of about 10 seconds. To be fair, it is a level on a spider web, and so I guess hidden traps were to be expected. At the same time, given the lenient save requirement, at least one can recover like I did, even when I lost one to the first hidden trap.

Harmless 19 - The Death Titan I mentioned this level as being one of the levels I liked visually. Mine, bash, done!

Harmless 20 - Treasure Island Another level I liked visually from the rank. Even though the exit is hidden, at least there are hints with the red X's. Plus, one can simply check the basher skill shadow being cut short.

Harmless 21 - Volunteers First! The first level with preassigned hatches, although this one took me a bit by surprise due to how there's no pickup skill label for the entrances. However, I know you found this out to be a good guideline to follow way after release and after the fact, and yea it would had been quite a task to go back to each individual level to do that. Lesson learned at least, because you at least did that for Lemmicks. Anyway, I didn't think this level was impossible like some members here did, as I let the first lemming from each entrance drop out and saw that one released floaters, while the other released swimmers. Plus, it should had been a bit obvious that at least one of the entrances releases swimmers given the skillset providing only platformers and bashers.

I did like this level, though. Nice puzzle where you have to realize that you cannot seal the water gap to the right until all swimmers have fallen into the water first, because they will splat otherwise. Probably due to this the level should be moved up a rank, but I think the level is fine where it is. Still not a difficult level by any means, although those who haven't let the level play out for the first few seconds would think it is impossible.

Harmless 23 - The Long Way Home  Nope, I guess I'm wrong, where this level is not in the Fun rank of the original Lemmings and certainly nowhere near as difficult as Mayhem 29, so I guess it's fine for the Harmless rank. Nice new solution of Mayhem 29 using the NL skills, although I made the end more difficult for myself than I needed to.

Harmless 25 - The Phantom Lemace Although the exit isn't in plain view, I think even without the exit sign it would had been obvious that it's inside the dome. Then again, not everyone is as observant as me, so I can understand why it's best to just add in the exit sign.

Harmless 27 - Loch Lemond Nice level and puzzle!

Harmless 28 - Gaze of the Basilisk Another nice level and puzzle! Definitely takes some thought to figure out how to hold back the crowd while one lemming forges the path. The only thing I don't like is how it's difficult to tell if it's radiation or slowfreeze.

Harmless 29 - The path of senses Umm, yea, wasn't too much of a fan of this level either considering that 39 gliders AND 39 swimmers had to be assigned.

Harmelss 30 - Triathlon I think there's a Reunion level with the same title. To close off the rank, even more repetitive skill assigning, but this time every lemming gets all 1 each of the 3 skills. I think levels like these with repetitive skill assignments gets old very quickly, so that's probably why the community hates these levels in general.

Not much to say for this rank either other than I think I enjoyed the levels here a bit more than I did the Harmless rank. Still a lot of pointless levels, such as

Disturbing 2 - We All Go Through Bash with each lemming as it comes up to the wall, although it stands out as the level with the most entrances/exits with 20 each

Disturbing 7 - Totally Diggin' this! Way too slow with just one climber, and plus I will sometimes do this solution for the Fun version, just with multiple climbers all at the same time, so nothing new here at all

Disturbing 8 - The Menagerie Other than no disarmer, not that much different and harder from its Harmless version.

Disturbing 9 - Shock Absorber Pretty much Mary Poppins Land several times in one level in regards to layout and building all those splatforms. Here, I don't know if it's supposed to happen, but I was quite surprised when my worker lemming walked through the fire pit without dying.

Disturbing 13 - Drink up me lemmings, yo ho! Other than the 100% requirement, not that much different and harder from its Harmless 20 version.

Disturbing 14 - The Titan returns! Not much different from the Harmless 19 version, as I have to do is simply replace the miner I used with two bombers. It was nice to see a great looking level return though, but the repeat is just pointless.

Disturbing 27 - You shall not pass Another pointless level that isn't too much harder from the Tricky 27 version other than using a stoner to contain the crowd and bombing the OWW.

Disturbing 29 - All lems must die More excessive repetitive skill assigning, although just with the two splat height entrances (which is what makes the level unique I guess, as I'm not aware of any other level I have played that starts with two splat height entrances), with the left one floaters, while the right one swimmers.

The rest of the levels of the rank were either ok or excellent puzzle levels.

Disturbing 4 - A staircase of skulls Probably my favorite of the rank.

Disturbing 5 - Torture Pit I like how you put a lot of traps from different tilesets and they make a single appearance each. Although it's still an easy level where you can just contain the crowd while a disarmer goes ahead and forges the path for the others, it's still a decent puzzle.

Disturbing 12 - We'll have to make up for those Hardest level of the rank that gave me problems. Any gliders that go back to the left and you're in trouble, as they're stuck in an endless loop from which they can't escape. I'm not sure if my solution is intended, where you have to clone a glider the frame just before exiting and at a position where they both can exit at the same time. Finding this position with the miner is quite tricky. Also, there's no point in 50 lemmings if only 20 of them will survive with a glider assignment each.

Disturbing 16 - The Wall (Part II) Clearly a reference to the POTUS and his wall that he keeps mentioning but hasn't done anything and his supposed promise of making "America great again." Also, I truly hope you are NOT a Trump fan. I'm not going to be happy if you are.

Disturbing 18 - Lethal Dose Nice radiation puzzle where the timing needs to be worked out, but fortunately walkers are provided to make it easier!

Disturbing 20 - The Olempic Games Ok, this one managed to be a bit challenging and hence more difficult and different from the Harmless 30 version. Decent puzzle where it does take a bit of thought on how to circle back to release the crowd, although even with the restrictive skillset it's not too difficult to figure out.

Disturbing 21 - Lemmigration Quotas Nice tricky puzzle here! I'm not sure if my solution is intended, though, as I have a fencer leftover. Also, unlike the original Lemmings, Fun 3 has a repeat in Paralems, although not an exact repeat due to the splitters, which the Harmless 3 version didn't have. Fun 3 was the only level in the rank that didn't have a repeat in the original game, too.

Disturbing 23 - Srpski level Not sure what the first level of the title means. Bit trickier than some of the other levels in the rank, although not too hard given the abundance of builders.

Disturbing 24 - Face the Hydra! The best looking level of the rank! It's like a Scylla monster. Ultimately, I went the easy way out by taking the bottom route and just had all of them be swimmers.

Disturbing 26 - Have you seen my screwdriver? Nice puzzle that is somewhat difficult and therefore appropriate for its position near the end of the rank. Not sure if my solution is intended or if I made the level harder on myself than needed, although the time limit seems quite tight on this level. Not a problem, though, since I love time limits in the game.

Disturbing 28 - Across the seven seas I probably made this much harder than necessary, particularly since I use the digger cancelling another twice in this level. Still, nice, somewhat tricky puzzle that's much different from the Harmless 5 version in that none of the lemmings are preassigned swimmers and so platforming across the water gaps is necessary.

Disturbing 30 - Point me to my training course Nice level to finish out the rank that takes some thought to solve. I might had backrouted the level, though, considering that I don't really make use of the bottom left exit. 

Ok, now we're finally starting to get into the tricky and more enjoyable levels, as I felt somewhat of a huge jump in difficulty starting with the first level.

Disgusting 1 - The Pit and the PenduLem Nice tricky level to start off the rank that requires some thought on the best route to take while also making sure that you're not being wasteful with the builders. I initially took the bottom route but ran into builder shortages and how to release the crowd.

Disgusting 3 - Funny little red buttons... Tricky puzzle to work out, but still a nice level. There's probably better ways than the way I solved the level, though.

Disgusting 4 - Thanks for the support! Other than fencing from the bottom of the OWW on the right side, not too different from the Mayhem version, although this level still manages to be slightly more difficult. Still, great puzzle that I didn't see as completely pointless.

Disgusting 5 - Snakes and ladders This is probably a huge backroute, although if one is familiar with the game, where ladders will get someone to the goal much faster, whereas snakes are the opposite, it's probably not. Ugh, again that hidden trap! Luckily, it's the only one. Still, I'm wondering how do you get the lizard trap to kill lemmings vertically instead of horizontally?

Disgusting 6 - Welcome to Hell! Whoa, those vertical pointing flamethrowers looks cool. I wonder if that's supposed to represent the devil. Also, you can destroy steel the way I did at the beginning?? Finally, my solution probably isn't intended, but I think this level is "anything that works here is fine" for you.

Disgusting 8 - Kentucky Fried Lemming Nice reference to KFC, which I absolutely love. Also, the writing in the level Nice, easy puzzle! It was somewhat cool seeing the solution in action.

Disgusting 9 - The deck stacked against you Not hard, just extremely repetitive and as a result very annoying and boring.

Disgusting 10 - Skies aflame I must say, I laughed when I was reading through the comments for this level in this topic from those who thought this level was "impossible" just because swimmers aren't provided. Of course, I didn't fall for this schtick and figured that the lemmings must be preassigned swimmers and was pleased to find my speculation confirmed when I let the level play out for a bit. Nice easy puzzle and level!

Disgusting 11 - One-man building company I like the concept in this level, just finding the right place to build on the ground and the right time to clone the lemmings was a bit annoying.

Disgusting 12 - Witches of Salem Nice level! Obvious reference to the Salem Witch trials in history. Look at all of them witches flying through the updrafts with their glider. At least no one got executed or burned.

Disgusting 13 - The collapsing tomb I knew this was going to be a "things don't appear what they seem," so in a way I was somewhat ready for hidden traps. As I mentioned before, I resisted the urge to activate CPM, so I just took the hidden traps as I went or in some cases I would correctly guess where the trigger was. It is a bit annoying, but at least the level's not hard and it is quite short.

Disgusting 14 - The docks Nice puzzle in figuring out how to get the crowds up with stoners and builders. Interesting how I managed to get the right place to bash to the exit the first time.

Disgusting 15 - Throw me a lifeline Nice easy puzzle! Once again, that hidden trap Then again, I guess the disarmer provided should had been a hint to one being present. Is this the level that fails before the "Let's go" sound is heard?

Disgusting 16 - Marathon miner Ok, I solved the first version in almost the same way as its repeat, so pretty much no difference here other than all but two of the blockers need to be released.

Disgusting 17 - Mary had a little lem Nice standard "blockers contain crowd while the worker(s) forge the path" level with a new solution to Taxing 2 with NL skills.

Disgusting 18 - In memory of Steve Irwin Really nice looking level and nice tribute to the crocodile hunter. I don't think my solution is intended, considering that I don't use the pick-up skills at all. I could had easily saved 100% here by not using the right side of the level.

Disgusting 19 - Filling the gaps I used the stoner staircase in my solution. There's probably much better and easier solutions, though. Nice ceiling solution, though, and good puzzle for a version of Pillars of Hercules in Paralems.

Disgusting 20 - Get your a**es of the fence Oops, looks like you meant "off" instead of "of" in the title. Nice puzzle and definitely trickier than the original version that requires some thought to solve. I'm not sure what purpose the cloner serves.

Disgusting 21 - Twilems Nice puzzle that requires some thought to temporarily contain and delay the crowd while the worker lemming platforms the gap. I like the moon here.

Disgusting 22 - Tower of Babylem Ugh, more stacker staircases. Repetitiveness of skill assignments is getting really old in this pack by this point

Disgusting 23 - Three waves of Lemminism Nice level! Some thought is required to get the bottom crowds up to the exit, but not too difficult to do.

Disgusting 24 - Diggy Liggy lo Another nice level and puzzle!

Disgusting 25 - Omnomnom! This must be the other half of the Scylla monster that the hydra looks like from the Disturbing rank, Charybdis. Nice short and easy level.

Disgusting 26 - The prison cells Nice puzzle where you need to be efficient in your builder/platformer usage, as even though they seem to be plentiful you can run out of them if you're being wasteful.

Disgusting 27 - Tidal wave Not too much different from Cascade other than using a stoner to contain the crowd while a worker lemming forges the path and builds the splatform.

Disgusting 28 - Circuit Training My solution isn't that much different from the Disturbing 30 version.

Disgusting 29 - Underwater Hangar Ok, I didn't realize there were invisible updrafts here at all due to how I simply built up to the exit. I only found out from the comments of others here.

Disgusting 30 - Apocalems Now Nice puzzle to finish off the rank!

Abhorrent 1 - The Walking Lems The first zombie level I have seen in a while. Nice easy level to start off the rank.

Abhorrent 2 - Lemming epigenetics I just realized that I could had done all of the splatforms at once rather than one at a time. Perhaps the time limit can be significantly reduced to enforce this. Again, cloning 40 times is pointless! Get rid of all but 5 of them and up the number of lemmings to 75.

Abhorrent 3 - Danger of breakthrough Nice puzzle where you have to time the assigning of walkers to make a small slowfreeze staircase in order to use one builder to bridge the water gap.

Abhorrent 4 - Journey to Emeria Pretty difficult level with the main challenge being to figure out how to use the builders in the level. Truthfully, after a couple of attempts I activated CPM just to make sure there wasn't a hidden exit or anything because it seemed impossible to reach the visible exit with the amount of builders given. Turns out that I didn't figure out the builders on the non-crystal platform correctly.

Abhorrent 5 - Don't lock me in! Nice somewhat tricky stacker puzzle!

Abhorrent 6 - Sneak past the guards Ok, I seriously thought that wasn't the exit in the middle there and that it was a find the hidden exit level. When I got surprised from mining and not finding any exit in the walls after a couple of tries, I then tried the middle. Guess I just need to familiarize myself with this tileset. This is still a really nice and easy level. Just two miners and a stack on both sides and done.

Abhorrent 7 - Inferi assault Nice puzzle in that the main challenge is figuring out how to contain the crowd and avoid the zombie threat. Once that is achieved, the rest of the level is easy.

Abhorrent 8 - Cave canem The trickiest part was avoiding the top trap. I probably just overcomplicated that part though.

Abhorrent 10 - Ready for takeoff! Nice level that managed to stump me for about 10 minutes. Nice red herring with the water gap where some might bridge that instead of using the builders to build up to the updrafts.

Abhorrent 11 - Pull the plug Nice level where the main challenge is figuring out how to dispose of the zombies. Once that is done, the rest of the level is easy.

Abhorrent 12 - Luring Lemmings into mouse trap Nice puzzle! Not trivial, but not too difficult either. I realized just now that I could had released the crowd as soon as the pioneer lemming collected the first miner pick-up

Abhorrent 13 - The untouchables Nice easy level. A bit too much building, but at least the repeat is more interesting.

Abhorrent 14 - Sustain the population Ok, this was an interesting concept of racing to clone a left-facing lemming 40 times before the zombies became a threat, but it's still too much cloning repetitiveness

Abhorrent 15 - Paving the way Not much harder than the original version, but at least you don't assign swimmers and gliders 40 times. The only thing I think is odd is how the lemmings didn't burn from the fire pit.

Abhorrent 16 - The opportune moment Nice somewhat tricky puzzle where you need to be efficient with your builders, as they run out surprisingly fast. Here, I thought the anti-splat pad was busted, and so I used the solution shown in my replay. That's probably because I didn't build or platform at the right place. I guess I forgot you need to be right on the spot with them and not just fall through the trigger area of it. A case of I need to reacquaint myself with the anti-splat object. Other than being efficient with your builders, the other main challenge is the tight time limit. It felt satisfying beating the clock on this level, actually. I am a lover of time limits in this game, after all.

Abhorrent 18 - The bee's knees Nice use of the digger-basher staircase in a level with no constructive skills. It is a bit strange to turn around by bashing into steel, but one must know that's what happens in order to turn the pioneer lemming around to rescue the crowd.

Abhorrent 19 - We are not invited? Nice short and easy level. Not sure if my solution is intended.

Abhorrent 20 - Help! Get the ratcatcher Nice level, but ugh again with all the floater assignments on the splat hatch.

Abhorrent 21 - Mafia methods Nice use of stoners to provide stepping stones to use builders until the exit is reached. It is a bit repetitive, but at least the level is short.

Abhorrent 22 - Who put that thing there? Yea, this level confirmed to me that I didn't build in the right place for the anti-splat pad to work correctly on Abhorrent 16. Nice, easy level where collecting the builder pick-up is absolutely necessary in order to complete the level. Here, I think I should had done it the other way around to lose less lemmings.

Abhorrent 23 - Buried knowledge Nice, tricky puzzle level with the main challenge figuring out how to get the zombies to disarm the traps and then to dispose of them afterwards while only 2 regular lemmings at most and not getting any more infected by them. I probably overcomplicated the solution, though.

Abhorrent 24 - Beam me up, lemmy! Ugh, that hidden trap at the bottom! Time was never an issue for me here at all, although it comes surprisingly close to running out. I certainly could had avoided that by releasing the crowd way earlier though.

Abhorrent 25 - Diggas in Paris The Eiffel Tower was one of my favorite places to visit when I went to Europe back in 2007. The design of this level is nice. Also, nice puzzle and solution of digging away the Eiffel Tower, although I shortcutted some of it. The exit isn't completely hidden, as at least the torches are visible.

Abhorrent 26 - Lems Going Their Own Way Not sure if this is intended, although at least not all the lemmings went to the same exit.

Abhorrent 27 - Resistance is futile The main challenge is figuring out how to avoid the lemmings getting infected by the zombie horde and disposing of it. Still, nice level.

Abhorrent 28 - Synchronised performance Nice puzzle. Not sure if my solution is intended, though.

Abhorrent 29 - Dispose of failed exemplars More challenging than the original version but still a nice puzzle figuring out how to contain the zombie threat and where the bomber holes should be so that the crowd can still continue to the right without falling to where the zombie horde is. Once done, the rest is easy.

Abhorrent 30 - Divided we fall Nice twist on Tricky 2 where the platform is in both directions and having each individual lemming dig, although in my replay I missed a couple of individual lemming assignments.

Demented 1 - A God's task Nice and easy no terrain level with infinite amounts of all skills to start off the rank.

Demented 2 - Aerial bombardment Nice puzzle that requires some thought and timing on how to get rid of the zombies.

Demented 4 - Rest for the Wicked Much more interesting than the original version with a nice solution.

Demented 5 - Under the bridge Nice tricky puzzle with a nice solution. Some thought is needed on how to contain the crowd, as well as realizing that the swimmer pick-up is a red herring

Demented 6 - ElemEnts This was also a nice tricky puzzle, especially with how to get the bottom crowds up to the exit. There's likely better and easier solutions than what I did, though. In particular, I avoided the slowfreeze completely, so that probably made my life a bit harder on this level. I do like how each entrance spawns a different special group: top left gliders, bottom left swimmers, top right disarmers (even though there's nothing to disarm in this level), and bottom right climbers.

Demented 7 - Shallow water. Diving prohibited Nice reference to the warning that swimming pools display at the shallow end. Harder than the previous two levels. I initially tried to make them move downwards with stoners to avoid the clam trap, but after a while I gave up on that and simply relied on compression to pass the level

Demented 8 - AlLemhu akbar! Probably one of the few levels where players will be so glad for timeless bombers, as each bomber has to be used right when the lemming touches the wall.

Demented 9 - Make yourself useful Wow, I like this level a lot. Really cool concept of releasing the right zombies in the right order with a bomber so that they can clear the path for the regular lemmings. In particular, releasing the swimmer zombie to provide a stepping stoner for the left-most zombie to detonate the trap and clear the way for a regular lemming to hit the button, and releasing the disarmer zombie first to allow the climber zombie to detonate the trap to clear the way for the top button. Once that's done, the rest is easy.

Demented 10 - Can you get it for me in time? Nice race against the clock combined with collecting the pick-up skills in time before either lemming is in danger.

Demented 11 - We're falling left and right The last of the infamous WAFD versions for the Paralems pack. Not that much different from the version in the previous rank concept wise, where instead of a splitter a cloner is used multiple times on a right facing lemming. Then the same solution as usual applies. Again, cloning several times is really old long before this point.

Demented 12 - Attack of the Clones Not sure if my solution is intended, particularly since I avoid the radiation completely and that the timer is long enough for the lemmings to exit before they can explode.

Demented 13 - Only over their dead bodies I really like this level as well. The main challenge is getting one zombie to use the radiation to blast a hole in the thin floor, while the other zombie avoids the radiation and uses the slowfreeze to provide a stoner stepping stone for a lemming to platform to the exit. Nicely done!

Demented 14 - It's Raining Lems - Hallelujah! Ugh, again with the repetitive assign a floater to every lemming Here, I did it just like that one level from Lemmings Revolution where pause is disabled. Easy and short level otherwise.

Demented 15 - Let Down Your Lems Obviously the title is a reference to Rapunzel and her long hair. The concept here is cool, but ugh, the repetitiveness of stoning to make a really nice long, high stoner staircase. Here, I worked on both ends. That part is easy to figure out, but it's still a tricky level trying to figure out how to get one of the bomber pick-ups and avoiding the rope trap.

Demented 16 - Break my fall Well that's not cool hiding the anti-splat pad. Luckily, it's right below the splat pad, and it's still probably easy to figure out that something else must be going on considering no gliders or floaters are provided. Still a nice puzzle. Not sure if my solution is intended, considering I have some leftover bombers and stoners.

Demented 17 - Detonate on collision This seems like a really bad backroute, considering all that's needed is one lemming to use the radiation and timing it to glide to use the correct updrafts and bomb a hole in the right place in the wall. Then again, it probably is intended and the rest of the skills are decoys.

Demented 18 - Halt the execution In contrast to the original version, this is a way more interesting level where you need to send one lemming each to save both splat hatches before you lose too many lemmings to splatting. There might be better and easier ways than my solution, though, considering that I was being quite wasteful with my builders.

Demented 19 - Maze of omnipotence This seems like a backroute, but I'm not sure.

Demented 20 - The Lempire strikes back Not sure what the purpose of the zombie horde is for, considering they were absolutely no threat. Also, I'm not sure if my solution is intended, since I have so many skills leftover.

Demented 21 - Isla de Muerta Very interesting variation of the original, where this time the regular lemmings spawn on the far left and right entrances, while the zombies spawn on the central island instead of the other way around. The zombies are no threat at all, considering that you don't even need to build past them, so the challenge instead is making sure you don't lose too many swimmers to the deadly edges

Demented 22 - No idea what you're thinking of Not sure what the purpose of this level is. Inverted terrain maybe?

Demented 23 - Parkour of pain Nice puzzle. Not sure what the cloner is for.

Demented 24 - Lake of the Dead Not sure if my solution is intended. The sound of swimming zombies got very annoying after a while, but I probably brought that on myself considering that I 99ed the RR pretty early while the path was still being built.

Demented 25 - Six heroes, one destiny Nice easy puzzle to round off the last of the plain levels before the final 5 of being special in some way.

Demented 26 - Trust no one Is this the ultimate trolling level you were referring to in the OP? If so, I say it wasn't that bad of a level, considering I solved it in just a few minutes. I initially took the top, but ugh hidden traps once more! Also, not sure if the lemmings are supposed to survive the hidden fire pits in the basher tunnel. With the exit visible and the pre-text for the level, I figured that it had to be fake steel, and indeed it's nice that my speculation was correct when I was able to dig through it. Once again, I didn't activate CPM at any time while I was playing this level just to see if the level really lives up to its trolling potential. So, I'm probably one of the few people where this level didn't make me rage at all despite not having used CPM.

Demented 27 - You can't even The level in the pack where no skills are provided and the only thing you can adjust is the RR. This one took me several tries and a lot of trial and error to determine the optimal RR. In several attempts I was short 1 lemming due to the time running out. Some more tweaking and then I was slow by a second. Then I finally succeeded and ended with 4 second remaining.

Demented 28 - Dark fate of Atlantis A level that's entirely underwater, a reference to the city of Atlantis sinking. Ugh, not only did that hidden trap take me by complete surprise, it also annoyed the heck out of me. I initially used stoners to push the swimmers down to avoid the needle trap. Also, I thought the exit on this level was busted for a really long time. I was so confused when the lemmings wouldn't exit when they were swimming on top of the water right where the exit is. I even tried making a stoner staircase and having the lemmings walk to the center at the top of the exit, and they still didn't exit. After a while, I activated CPM just to make sure what I was trying to do was really the goal/exit. Indeed, CPM is of absolutely no use here, as you can't even see the trigger area of the exit. I remember I was about to report this level as broken to you, but I'm glad I played around with the level some more and was finally able to get them to exit. Turns out the trigger area is really down there where the floor is.

Demented 29 - IT'S FEEDING TIME! Ok, I definitely made the solution a bit more difficult than it needed to be. I think in Old Formats it's possible to disarm traps while platforming/building, but in New Formats it is not possible to disarm, so there's definitely inconsistencies between Old Formats and New Formats. Then again, I believe that happened in a United level, so maybe not completely inconsistent. Somewhat nice looking level with an abundance of traps everywhere. Even then, what makes this unique as part of the final 5 levels of the pack?

Demented 30 - Winter is here Ok, not sure if you intended for the player to find some way to kill all the zombies so that the regular lemmings are completely out of harm's way before forging the path to the exit. I guess the 80 RR was just right to still get the zombies killed by the icicle trap, as the second nearby zombie nearly gets by without getting killed. Even then, the time limit is quite tight if you wait for the glider zombies to die first. So I guess what makes this level unique for the final 5 levels is how it's full of zombies?
