Instead of building on top of the tree on Calm 6, I now just need to have the Lemming drop down to the steel and then start building up to the egg. Tense 4 also fails for this same reason as my worker doesn't build on top of the tree, but that's ok, it's not that big of a deal for me to manually recreate my initial solution for the level

Calm 2 - The Stumbling Block Probably a little too difficult for its position despite only two skills available. I was a dummy here and for some reason a few times tried simply digging with the first Lemming after the basher gets far enough to get past the block at the bottom It's likely possible to be able to have everyone who makes it into the digger pit survive, but I honestly probably gave up trying to fiddle around with that too soon

Calm 5 - Status Quo Nicely designed by your friend but other than the VGASPEC like level nothing too special and very easy.

Calm 6 - Your Egg Is Cracking! Hehe, I like the design of the egg with the exit partially buried in it I'm a bit annoyed that it doesn't seem to be possible to save everyone due to the builder staircase just barely not reaching high enough to stop the splatting on time, but well, it is what it is. I'm just one of those players who likes going for save all's as much as possible, and if that's not possible then saving as much as is possible

Calm 7 - The Lemming Hair Dryer Way too easy. I would definitely swap Calm 2 with either Calm 5 or this one, though it's probably better to swap with the latter, as the halfway point of the rank seems perfect for the VGASPEC level

Calm 8 - Follow Me! Harder than it looks, though that's because for the gaps where the wooden staircases are I kept trying to not use any interrupting skills Even then, the second Lemming catches up quite quickly and hence it's necessary to either delay him with the other skills and/or also have the lead Lemming build across the gaps as quickly as possible while also cutting him off early once he's made it over the other side. Nice level nonetheless!

Calm 9 - Sneaking Out Needed to resolve this one, as one of the early skill assignments comes about a frame too late or so. Phew, nearly ran out of time, I think I was just a frame away from the clock ticking down to 0 seconds

Calm 10 - Break the Cycle I remember the contest version of this level from 5 years ago. Sorry to hear that it needed to be scrapped from the pack I remember it being a nice one despite it being an easy one. This one's easy too, though I think my solution to the contest version might still work here too. I would have to check.       

Tense 3 - Going Down Now this would be a good example of one where it's easier than Calm 2 but still not trivial by any means. Once again, I was a dummy of having the digger face the wrong way when I was doing it on the right side, as after a few attempts I went down the left side. You can actually go down either side, just if you do it on the right make sure the digger is facing the left, not the right! Nice level!

Tense 4 - Operation Hatchling Easier than the original in the previous rank IMO, especially as you have more builders than you actually need this time unlike the last time. Still a nice level here

Tense 6 - Pause and Ponder I haven't tried or checked, but I'm guessing there's a hidden exit on either side. I went for the right exit. Nice challenge to save everyone here, though it's still not too difficult. This one is a bit harder than the VGASPEC level in the previous rank, but still a nice one. Your friend did great.

Tense 7 - Meet in the Middle Nice Cascade concept level. Nice level idea with a glider going over the top to dig and build to the exit to turn and then build from the right side while also having another Lemming build from the left side later on, with some timing needed in order to turn the glider back around towards the exit.

Tense 9 - Risky Business This one I needed to resolve. The leader in my pre-testing replay gets killed by the shredder trap here. Looks like it was a backroute according to what I saw in my replay Just turned around with a bomber this time and I believe the rest is the same.

Panic 1 - Help is on the way! Repeat of Tense 7 and probably a bit easier. The only real difficulty is being quick enough to save the hatch before you lose too many due to splatting, but I think the timing always naturally works out here.

Panic 2 - Lemming-lime soda Wow, nice level! I like how the climber/swimmer needs to come from the other side to get the others out safely. Here, I was a dummy because I thought you needed to go over the green pail as the handle looked like it's too high for the others to step up through Hence I originally tried building and blocking to build the other one, but turns out that's not necessary and hence you can just lose 1

Panic 4 - Freezer Burn Another nice level and concept of having a danger hatch over the steam blower trap of the Ohno Snow graphic set and hence you need to get Lemmings from the other entrance to make safe landing platform for the danger hatch. Even with that, quite an easy level due to the lenient save requirement and plenty of skills available. Probably could squeeze a few more saves in my replay, but meh, couldn't bother myself to go back and tweak it

Panic 6 - Lemming Replacement Therapy Probably just as hard as Calm 2, though the level concept here is nice too. I challenged myself to get the two miners to cancel each other out at the bottom and hence make it a lose 1 solution. I would just keep it a lose 2 level, as this is super fiddly and very precise. As Armani once said of me in his Lemmings Uncharted for a talisman he tributed to me, "don't try this at home if you're not kaywhyn"

Panic 7 - Be the girl you wanna be Nice final special VGASPEC of the pack. Definitely the hardest one of its kind but still a very nice challenge to go for a save all

Panic 9 - A Death-Defying Stunt Like the original, I needed to resolve this repeat as well. I believe it's the same as my pre-testing of the updated version you sent me in that I was able to spare a shimmier here as well. I personally would probably leave some more wiggle room to allow successful shimmying at the start, as it seems quite tight and visually appears like they won't be able to get past the blocker, but that's just me    

Fun 2 - What's wrong with this picture? First hidden exit of the level. As mentioned before in the General Feedback heading, consider putting some kind of visual indicator to mark where the exit is. You can probably tell why Tricky 28 isn't as hated as most other hidden exit levels despite it being most players' first experience with a level that contains a hidden exit, and that is simply due to it being super close to where the Lemmings start on the level.

Fun 5 - Lollipop from Hell I was kind of bummed out that it's not possible to save 100% here Just my playstyle when it comes to Lemmings. You don't have to change this at all, just letting you know I like going for save all's as much as possible when playing Lemmings

Fun 7 - Lattice of Frustration Yea, not a fan of repeatedly assigning floaters for the right entrance. However, I of course didn't have to do that, since the save requirement is just 50%. It's still an easy level regardless, just one part with needing to repeatedly assign floaters I wasn't a fan of

Fun 8 - Take it up to 99! Nice level to finish off the rank! This was probably my favorite in the entire rank It was fun to beat the 1 minute time limit even though it's still a very easy level despite it. Well done  

Tricky 2 - Invasive species Nice use of the ONML traps on a Just dig variant Looks somewhat intimidating due to the chameleon traps but it's still an easy level thanks to a huge skillset. Still early in the pack anyway

Tricky 3 - Lapland New Forest Yup, I was able to find a 100% solution for the right exit

Tricky 4 - I'm a lemming - get me out of here! Aww, that poor Lemming on the far left stuck with various pointing arrows surrounding the terrain Still a nice easy level, though the first where I encountered some really annoying one-pixel gaps that need to be built over that are hard for me to spot.

Tricky 5 - Shabbot Shalom, Mr. Lemberg Wow, nice looking level!

Tricky 6 - War - what is it good for? Excessive bombing isn't my favorite type of level to play either, but this one at least players have the option to play with untimed bombers. It's still not too difficult of a level with timed bombers, but yea, those days are pretty much of the past for the most part Besides all the bombing, quite a nice level with the one miner and basher

Tricky 7 - The Passover level I'll be honest, and that is this level felt quite long and seems like it doesn't have any good reason to be long other than the nice decoration you put in the level Here, where the Lemmings fall even though it looks like they should walk on the terrain just fine is a bigger problem. IIRC, I'm very confused why the Lemming fell off the bottom right where the ONML Rock set is used just shortly after the Pillar rope trap. Also, more of a question for WillLem, but is there a way to scroll faster on the mini-map?

Tricky 8 - I'm a lemming - get me out of here! V2 Same as Tricky 4, except there's more than one Lemming trapped on the far left.     

Taxing 1 - The fun police Nice blockers only level! My main point of criticism is it's hard to see where the Lemmings can go at the bottom, and once again what looks like the Lemmings can walk fine there's a really small and very hard to see gap. Also visual tidying up, but I think you said you planned to fix it up anyway because of how you messed up the design. I get it, a lot of the time my levels don't end up like I envisioned in the layout

Taxing 2 - Archaeological Tour III Now the arches at the top is used due to an entrance being there. Much harder to get up the level than in either of the previous two iterations of the level, but still a nice level

Taxing 3 - Stop digging? I will NEVER stop digging This looks to be the I am A.T. variant you were going for. Even then, this one is nowhere near as annoying as the Sunsoft level from the Genesis/Mega Drive port of Lemmings. This is quite a nice level!

Taxing 4 - Does this look familiar? Ahaha, climbers available for all but that one poor Lemming who can't get one because there's not enough. Very nice puzzle rescuing that non-climber, just way too much climber assignments for my liking. Consider reducing the number of Lemmings and accordingly the number of climbers, like 10 Lemmings but only 9 climbers, for example.

Taxing 5 - Trapped at the reptile sanctuary Very nice design using the ONML Rock set! It's one of my favorites, though ONML Bubble is my top favorite. Once again, a really annoying very hard to see gap right where the exit is

Taxing 6 - You gotta be avin a bubble! V2 Pretty much a way more extreme version of Fun 7 but thankfully you don't have to assign everyone a floater on the right and simply can stop once the splatform is made. There's nowhere enough floaters for everyone anyway. 300 Lemmings is definitely way too much here and the level serves absolutely no purpose with having that many. Once again, consider reducing the Lemming count drastically and adjusting the skillset accordingly

Taxing 7 - Doom Spiral Not sure if you're aware of the digging and building across trick. In particular, I'm not sure it even works on the Win95 version of the game. Even then, alternative solutions exist to the level.

Taxing 8 - Everything about this is wrong Very nice design with the Sega style! Interesting level where everyone else splats after all floaters are used, but even then you're allowed 30 losses among the 100 surviving floaters. The amount of bombing needed here is at least of a moderate amount and not too excessive. Other than that, nice level to finish off the Taxing rank!      

Mayhem 1 - Living on the edge Yea, way too much excessive building spamming needed at the very start for my liking. Here, I was somewhat of a dummy with trying to contain the Lemmings at the start on the layer of the star, and while that is an approach you can take, it won't be possible to save the others from falling into the water after freeing the blocker since it's not possible to get builder terrain underneath them this way. Or, it is possible, but it would require a lot of digging building like you see on Taxing 7.

Mayhem 2 - Purimschpiel Very nice builderless level! Another hidden exit level, but thankfully the last one in the pack. Here, my main criticism would be how it's very un-intuitive that the climbers can get over walls that look like they'll hit their nose instead. In particular, the part right before the three steel blocks in the middle, I kept trying to bash before he started climbing, only for him to turn around every time because he detects steel and turns around. You can't afford for this to happen because you need to save everyone. Or rather, you can't have him turn around at the bottom. It is necessary to turn back so you can mine to get the others up later on. Once again, consider putting a visual indicator to mark where the exit is hidden

Mayhem 3 - Aren't you the brave one? Interesting looking level and one that looks much harder than expected. There's some approaches that look like they could work but at least I wasn't able to get a working solution. This is another one that felt pretty long to me due to the large size. Still a nice challenging puzzle with figuring out how to traverse the map safely and get everyone to safety!

Mayhem 4 - Have a bash at it go on Hardest level of the pack as I mentioned before. In particular, I figured out the route to take somewhat fairly quick, the hardest part is at the bottom with being able to make the route in such a way that everyone can get onto higher ground so that they don't turn around, which again you can't afford due to the level requiring a save all. I was actually taken by surprise that you can stop the previous basher with one other basher if you do it at the right spot. I'll have to check SuperLemmini here, as I'm sure two bashers can go together without the other one stopping in the same situation. If two bashers are possible there, then this is a mechanical difference between SuperLemmini and RetroLemmini. Nice bashers only level here that manages to be quite difficult. Only other point of criticism is the dependency on the level boundaries.

Mayhem 5 - Archaeological Tour IV The 4th and final iteration and hardest level of this kind that has repeated once in the 4 main ranks. The hardest part is getting the bottom entrance up to the exit while also keeping everyone safe since you need to save everyone. I initially went over the top with a worker from the top entrance, but seems he reaches the ceiling too soon and hence can't make it over the water. Here I encountered an annoying thing with the replay feature where when I'm playing I build to stop the digger at a point so that everyone is contained in the pit but when I restart the level he all of a sudden builds at a time so that it gets everyone out. Seems to be a replay sync problem/bug here.

Mayhem 6 - A Glimmer of Hope Nice level but once again annoying very hard to see tiny gaps here! Kept having management problems here, but that's my own fault with not watching or doing things properly on the level

Mayhem 7 - Welcome to Builderfest Yea, way too extreme on the huge amount of building needed so that you're able to save enough despite the many losses you're allowed. As mentioned, I nearly skipped the level but I persevered and was able to play through it and get it solved

Mayhem 8 - Tiles of Torture Nice level to finish off the pack and certainly nowhere near as hard as some of the previous levels.       

Calm 2 - Training Day Nice one!

Calm 3 - We Are Lem-Bob-Omb! Personally I'm not a fan of excessive bombing levels, but the challenge talisman is still quite interesting nevertheless!

Calm 4 - Emerald Cave Another great talisman! Interestingly enough, this one took me some time to figure out, though apparently I was already on the right track with turning the second Lemming around earlier by building into terrain but simply didn't realize it at the time I thought the first Lemming to build across the first gap would be able to do a lot of the work before the others arrive, but nah, turns out it's not possible without going over the total skill limit.

Calm 5 - Better Run For Shelter Wow, I really love those bombs pointing down indicating they're falling from the sky that you put in the level Reminds me of that one meteor level from Apjjm's Lemmings Quartet pack. The first level in which I got the talisman on my first pass even though I didn't open it up to see the requirement Looking back, I definitely could had easily used just 4 builders here, though I think the talisman isn't possible without that digging immediately upon laying down a builder brick so that he can build to turn around trick.

Calm 6 - Lemming Falls I went down the corridor before the gap, but looking back at the level I can definitely see the first approach I tried also being viable, as I could had simply make the splatform for the others with just one climber by having him build once he dug out all the terrain in order to turn.

Also, as an extra challenge, I now see there's even a no digger solution and hence the talisman could possibly even be changed to that in a future update!

Calm 7 - Lemstones The second level which I got the talisman for on my first pass, but that's because I'm one of those Lemmings players who loves going for save all solutions or if that's not possible then to save as much as possible As a matter of fact I pretty much went for save all's as much as possible on my first pass of these levels and sometimes I was lucky that it's also the talisman requirement. Think I even tried it on the PimoLems version but didn't succeed? It's probably not possible to save all on that version of the level anyway, but I might be misremembering.

Calm 8 - Cloud-Covered Stalactites Aha, I thought the talisman was no blockers, only I ended up using one on my first pass because the timing didn't work out the first time for me. Really good one here! This one's even better than the PimoLems version especially as it's a builderless one and that tends to be my favorite level type in the game! Not only that, it's far more interesting with just blockers and bashers.

Calm 9 - The Strange Relics of Lemnos As already mentioned, this was my favorite level! This reminds me of one of your first rank Fiat Lem! levels that had lot of bashers. Well done here, definitely a far better level than the PimoLems one!

Calm 10 - It's a Kind Lembourhood Aha, no diggers here in contrast to the PimoLems version which was an X-of-everything in all classic 8 skills. Definitely an easy talisman, though still have to be careful as skills run out quicker than they appear despite having a huge amount of miners and builders.

Calm 11 - Minimal Design Once I realized that you can lose up to half, the talisman wasn't so bad, though it's definitely still a challenging one to figure out. Nice one nonetheless!

Calm 12 - Ancient Crash Site Hardest talisman by far, though I kind of figured the bashers needed to go in the middle sections fairly quickly and hence the hardest part for me was figuring out how to get the crowd over there by going to the right at the top. Indeed, I kept thinking to mine through the emerald that connects to the ceiling through to just the two short ones immediately to its left while building the crowd to get over the first two. However, this then leaves the problem of the climber being stuck in an infinite loop and hence you save all but one, which is no good for the talisman. Took me some time to see that it is indeed possible for the miner to go all the way to the first two emeralds as well while allowing you to save a builder to turn the climber so too can go to the exit along with the others. It's probably a little too heavy on the precision with the miner, though the builder/miner combo always is.

Calm 13 - The Italian Job The funny thing was that my first pass had me go for a diggers only solution while going for the save all. I totally laughed upon seeing the talisman requirement because it was the complete opposite of what I attempted! This one's quite an easy talisman to figure out and much easier to execute than the diggers only solution I tried even though canceling a miner with another one is itself timing heavy. Nice level!

Calm 14 - Pagoda St Another one whose talisman isn't too difficult to figure out, though just like Calm 10 skills do run out much faster than expected. However, using the diggers wisely will help even out the miner and builder usages. There's that fire in the rings just like in the PimoLems version of the level!

Calm 15 - Standard Test Chamber Nice level whose talisman can be somewhat challenging to figure out but it wasn't too bad for me. Kind of helps that I've already seen this trick before in a few other levels. I did try going through the bottom, but I quickly abandoned that approach upon seeing that someone needs to go over the top to dig them out the far left side, which would mean more builders and more losses than you afford for the talisman.

Calm 16 - Voltaic Mosaics The third and final level which I got one of the talismans on my first pass, but again that's due to me going for save all's as much as possible when playing Lemmings. The one miner talisman is far more challenging but it's still not too difficult thanks to the very lenient save requirement. Also a remake that uses a NeoLemmix skill.

Calm 17 - What happened in Sovogda? Not familiar with what the reference in the level title is. That's a really nice sun at the top of the level, if that's what it is Took me some time here to figure out the talisman, but once I realize bombing a faller which frees up a bomber that you otherwise would use to get into the first open window at the start, it wasn't too bad. First zombie level of the pack from what it appears.

Calm 18 - Clumps I can up you on the talisman here, as I was able to save all but one I do believe the PimoLems version was a builders only one?

Calm 19 - Iron Industry Wow, this looks really amazing design-wise! Another level with NeoLemmix skills. It was hard for me to tell what the pickups here were. So, looks like it's not just you and Guigui. The talisman is a bit imposing, but it definitely makes it clear that getting the pickups are required and so isn't as hard as it appears. The challenge then is to figure out how to get them.

Calm 20 - Spring Break Really love the talisman here! Definitely reminiscent of some Pickaxe levels from PimoLems that made very good use of the miner skill. I originally got a save 98 solution and hence beat the requirement by 1, but I quickly went back and improved it to 99. Looks like Icho got me beat here by getting a save all. Darn it! However, I think I can see how it's possible and that it simply requires me to mine at a different spot at the top on the left side of the level.
