Emerald Cave - Same solution as kaywhyn if I remember correctly. I fixed this one along with other backroutes that were found. Your comment about the intended solution is indeed spot on! Hopefully there won't be many backroutes left after my fixes.

Better Run for Shelter - Someone else also solved it that way (may have been kaywhyn here again). This backroute made me scratch my head to find a fix but an idea came to mind watching your replay. I could limit diggers so you couldn't use one on the stairs to make the worker turn around. 4 diggers total seem enough to solve the talisman. Will have to do some tests! I don't like to limit too many skills for talismans because it quickly becomes an ordeal to remember all requirements. But limiting only builders and diggers should be fine

The Strange Relics of Lemnos - You solved it as intented but I had to leave a comment anyway, well done!

Minimal Design - This one felt rather straightforward to me but seems to give players some trouble! I may change the talisman color from bronze to either silver or gold

Ancient Crash Site - Perfect! As usual in my levels, I try not to leave precise skill placements to chance. It's the case here for the builders, you can set them at places that are easy to remember, but I may be the only one to see it

Pagoda St. - This is actually the route I use in my solution. I like it

Standard Test Chamber - Amazingly, this is almost a carbon copy of my own replay! Except for the fact that you had to use a basher at some point to delay one of your workers. Very well done! I still have to fix backroutes here, not sure how to approach this. Also thinking about removing one of the cubes because the as Guigui implied, the companion cube is supposed to be unique right? Glad you liked the Portal theme

Voltaic Mosaics - Interesting reversed one miner solution here!

Clumps - You actually got a few elements of the intended solution here. Will have to think big time to fix this level. Removing walkers seems mandatory.

Iron Industry - Your solution is very efficient, I'm impressed! Too bad there aren't enough climbers to save this extra lemming. I will increase the climbers pickup amount to reward players that want to go the extra mile I had a great time making this level. It's very different from what I'm used to make.

Spring Break - 100% solution here again. This needs to become the new requirement for this talisman

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
