01: Close to intended. As long as you compress the lemmings somewhere, I'm fine with that. The ketchup and mustard bottles aren't traps by default. It's just my evil genius that turned them into traps. Usually, only animals are deadly in my levels... but as you've seen from the occasional lightning bolt that can hit a lemming out of a thunder cloud (e.g. on "Lems in the sky with diamonds"), it's not entirely restricted to that.

02: That is a slight backroute, but a clever one. Maybe I can fix it, maybe not. I don't want to go all out on pickup skills on this particular level, since that's what Flopsy's second level, "Read my lips", is for.

03: Open-ended. This isn't based on any actual level by Proxima; it's based on his own verbal description of his level building style. Funnily enough though, as you can see from the past pages of this thread, he nevertheless was the very first one to identify his own level.

04: Intended. If you watch any Let's Play by Colorful Arty, you immediately know this level is his.

05: This level is a gift that keeps on giving with regard to backroutes. A little steel should fix this particular one, though.

06: That solution was much more complicated than the intended one, because you had the worker lemming loop around quite a few times. Still, you used all the skills, so that's fine by me! Now I can understand though why that crackle sound was annoying you the whole time, because the level took much longer with your solution. FYI, the New-Formats version doesn't have this object anymore, since it's technically an animation with no effect. And probably also because it disguises as terrain, and is therefore similarly dishonest as a hidden trap. I think namida has plans of reintroducing no-effect triggered objects, but that still doesn't mean this particular "trap" will return.

07: Intended. Just like IchoTolot's solution. Glad this approach seems to be sufficiently enforced on this level.

08: Open-ended. This is one of the levels not made in-style of IchoTolot, but a level type that IchoTolot hates (like a Hard-for-Flopsy level for Flopsy). That's why, in contrast to Groupie 03, I made the chambers interact with each other via the teleporters, as a compromise.

09: Valid alternative solution, includes the main trick.

10: Open-ended.

11: Well, that's one way to do it. As long as you use compression method and the chain staircase at the end, the level has fulfilled its minimum requirements.

12: Very nice and elegant! Btw, if this had been supposed to be GigaLem's level, I would have used his updated version of the Tree tileset. I used the classic one on purpose, because that's the one namida originally made. Also, the title is not misspelled, but written to emulate a New-Zealandic accent. If I had wanted to be particularly infantile about this, I would have called the level "All hands on deck!" instead. Though in the meantime, I've heard that this type of childish humour is actually something namida enjoys himself quite a lot, so maybe that could have been considered another "signature element" of his...

13: Not as bad as IchoTolot's initial backroute, but still too easy, you're right. At least you didn't use the Bomber to create any shortcuts. That gives me hope I might be able to stop this with a few more one-way arrows.

14: Different than intended, but not a backroute per se.

15: Open-ended. You used all the skills except for the last 2 Platformers, this is fine by me.

16: Yes, compressing the lemmings with the Fencers is intended. However, I never knew that it could be done inside the Fencer tunnel itself! I always compressed them while still on that flat surface of the wooden platform right under the hatch, and only once they had been compressed did I send them up by fencing through the stack. I guess I didn't think about this possibility because Arty originally did this with Bashers, and with those, in-tunnel compression won't work, because the tunnels are wider.

17: Intended. The SubLems level in question is "I am R.T." (pronounced like "Arty"), which is Arty's take on the Sunsoft-rank original Lemmings level "I am A.T.".

18: Valid alternative solution. I've come to accept that this level does too many things at once to specifically enforce the trick it's hinting at. But as you said, you used all the skills, and if it still worked for you to recognise this level als Pieuw's, that's all that matters!

19: Well, as simple as that was, it still required most of the skills. Maybe I can prevent it specifically by putting a small piece of steel right under the cross you used to have the Zombies walk over the Digger shaft. But if it's still possible to just dig anywhere else after that, this one might be difficult to fix.

20: Open-ended. And as you can see, no ketchup or mustard traps here!

Groupie 21 - Kiwi knights in white satin Very nice level and puzzle! I really like this one. Not hard, but not easy either. I had a feeling this was zanzindorf's tileset.

Groupie 22 - We are yung Obviously this is yung's design. I have also played his first and only pack, where I agree with you there are too many walkers provided for releasing the blockers in his pack. No real challenge at all. Similarly, this level is way too easy with the abundance of platformers and builders. I ended up getting over the OWW through the top.

Groupie 23 - The Earth Song I incorrectly thought this was a Nepster design, but now that you mentioned it's a bulletride design, yes I do see the Walk in the Park level design here. I don't recall the other level of his that you also put in here. I need to dig up that pack again. It's been a while since I solved all of Lemmings Stampede. Another great level. I'm not sure if the miner cancelling trick is required, although I can't thinking of any other solution that wouldn't require it.

Groupie 24 - Dove is in the air Ok, I definitely would not had guessed Dodochacalo here, although I also incorrectly guessed him in an earlier level in this rank. I'm sure I backrouted this level, considering that I have plenty of skills leftover, the only trick I make use of is a digger cancelling another digger, and I simply use the first few climbers as delays to give the builder enough time to bridge the gap to the exit.

Groupie 25 - Part of ze Reunion I definitely knew this is Icho's, since yes he's known for his Reunion pack. Not only that, the City tileset 100% points to Icho. Somewhat difficult, but it's not too hard. Nice level as well. I definitely don't like how it's difficult to see stuff in this tileset though. Skill shadows definitely came in handy to see if the structure on the far right would stop the miner in my solution.

Groupie 26 - Clam-a-Lem-a Ding Dong I definitely knew from the level title that this must be Clam's. That reminds me, I still need to play clemmings. Perhaps I can LP that one after the ones I have planned. He appears to have also vanished from the forums, so I haven't gotten to know him at all. Ok level, also a bit difficult, but not too hard. The fiddliest part of my solution is the drop before the exit at the very end.

Groupie 27 - Deceit and destruction I also knew this is Deceit's from the level title. I have played and beaten all of Deceit's Lemmings, but it was a long time ago and on Lemmix. The final Mayhem level was also one of the last levels I managed to solve after a while. I couldn't beat it at first, but I eventually was able to figure it out on my own. Difficult only due to the 2 builders, but it was still easy for me. Digger cancelling a digger for the win again

Groupie 28 - Hiroshima Now it's time for Gigalem. Here I thought this was yours, though, since I remember you doing a Japan level earlier in the pack. Should had realized it from the tileset that this level is Gigalem's style, although to be fair I haven't played his Millas' packs yet. This was a pretty cool and great radiation level, I thought. Solution isn't that hard at all despite the radiation. I don't mind radiation/slowfreeze, though. The only hard part of the level is the end where the zombies are. Correct me if I'm wrong, but the radiation at the end is placed in such a way that the lemmings will never explode before reaching the exit? I think the only way for that to happen is if the lemmings have far to drop down, giving the timer more of a chance to actually expire.

Groupie 29 - Every Geoff you take Obviously Geoff's style from the title, and I recently finished my second playthrough of his Geofflems pack. Very nice level here too! I especially loved the building to turn around trick and digging through the staircase to drop to the exit level near the end with the worker lemming.

Groupie 30 - Joga I definitely would not had guessed mobius at all. It's been way too long since I completed Mobilems. I first solved all of the pack on Lemmini, so perhaps I should revisit the pack for NL. Easy level.

Groupie 31 - Ya ochen rad Title definitely escapes me, and I certainly would not had guessed Gigalem. I really like this puzzle/level! Definitely requires some thought to solve. It's a bit difficult, but not too hard. Very nice solution. I had a feeling there were hidden masher traps, and indeed there are.

Groupie 32 - Fernando I knew this was Fernandes' style from the title. I have also played his master's degree pack from earlier this year. Starts off easy but definitely got hard as you progressed in the pack. Pretty easy level here. Nothing too special.

Groupie 33 - We don't need another hero I definitely would not had guessed Deceit here. I thought it was either a namida or a Nessy level. Both are wrong This level stumped me for about 10 minutes. In particular, the builder gap is such that the worker lemming will never turn around, so the challenge was figuring out how to get the crowd out before doing so. Still a really nice 1-of-everything level. Not sure if bashing against the OWW to turn around is intended, though I can't think of any other solution that doesn't require it.

Groupie 34 - I see fire Definitely not in a million years I would had guessed kieranmiller. I have not played anything by him at all. As for the level, this was a bit difficult, especially the beginning, but level's not overly hard. The rest of the level after the beginning is easy.

Groupie 35 - Fly me to the moon I would not had guessed Arty here either. I believe it was thanks to your Pit Lems pack that I learned the Moon object is actually solid. I always thought it was background. Just from the level title itself it's very obvious where the exit is. No real challenge at all here. Very easy level. Nice looking level too.

Groupie 36 - What does the fox say? I definitely didn't have Gronkling in mind when predicting whose style this is. I thought it was a Gigalem one or possibly someone else (don't remember who). Other than his Lemmini minipacks, I haven't played anything by Gronkling. He hasn't released any level pack yet, I believe? I wonder what's the status on his Lemmings Evolution pack now that he has returned from a very long absence. I'm very positive my solution is a backroute. I'm sure it's not supposed to be that easy This was even one of the levels you changed too. Looks like you have to fix it up some more.

Groupie 37 - Johnny B. Goode The B in the title totally escaped me and didn't point me to bsmith. I have played his small pack about a month or two ago, though it was my second playthrough (my first playthrough of the pack was several months ago earlier this year). You're absolutely right about him remaking several original Lemmings levels, as I also noted that in my feedback to his pack. Very nice no builder level/solution! This one was easy for me. Even after figuring out the solution, the other thing that also needs to be figured out is how to stop the climber from splatting after mining the crowd out.

Groupie 38 - A Mazu Grace Obviously the design is the author of Mazulems. Mazulems was pretty much the first full custom pack I have ever played, though I believe this was back when I was a high schooler and on Dos. My first custom pack on other engines was Dovelems on Lemmini several years later. I really like the solution here! I thought it was quite clever sending two climber lemmings to bridge the gaps from the other side before releasing the crowd. This was an easy level for me. The only part I don't like is how part of the steam is touching the lemmings through the builder staircase at the end. Seems that lemmings are fine if it's the end that touches them since they don't get killed.

Groupie 39 - Not the incended solution It definitely escaped me that this is your design style. I think I also agree with the community that your levels tend to have backroutes abound, although it's just like you said, you didn't have anyone test your levels/packs before you released them. You changed that with LOA. This was a really easy level despite how I was taken by complete surprise with the hidden traps in the skull. I definitely should had known those creepy looking eyes were traps.

Groupie 40 - The Grand Puzzle To finish off a very well-done and the largest level pack so far ever released is a very large level. I have not played Nepster's Final Frustration level yet, but I knew this level was his style given what I read about the level in the level pack topic. As a matter of fact, I still need to go back and finish solving Nepsterlems. I'm currently stuck on the first level of Black Hole, so I think at this point it'll be amazing if I manage to solve even just one level in that rank

Anyway, as for this level, truth be told, I initially was very intimidated by the extremely large level size. The high RR definitely didn't help matters once I started playing the level, but once I managed to stop those entrances that are heading into immediate danger, the rest of the level wasn't so bad. Needless to say, the first several skill assignments have to be extremely quick. I'm not sure how many, but I believe it's the first 15-20 skill assignments that need to be quick, so the beginning is definitely the most stressful part. However, as I just said, once you successfully manage to do all of that, the stress is eliminated and then you can take it a bit more easy. The level still doesn't become a whole lot easier, though.

I think as is true with almost everyone here and on difficult levels, builders is the skill that we all try to conserve as much as possible. Indeed, when I had made a lot of progress on the level and neared the end, I realized that I was running out of builders very quickly, and so the first thing I did after that is to find the places where I used more builders than was necessary and hence save rather than waste them instead. The destructive skills also surprisingly quickly, though I think the bashers and miners are the more problematic ones than the diggers. Due to the extremely high save requirement, it can also be really difficult to save all the blockers, especially the ones that are headed the wrong way. I think the most difficult area for me was the exit area, especially in regards to how to prevent climbers from going out to the right and dying. Also the area with the gold pillars with the two very tiny gaps can be difficult and very fiddly. The second right-most entrance area can also be difficult. After doing what I did by mining right away, I definitely could had made it easier by digging first. It's just that I didn't know where two builders would reach to seal off the gap with a lemming from the right-most entrance.

Several tricks are needed here: Digger-basher staircase, good use of delaying tactics without using builders, and either miner cancelling another miner, basher blocker turnaround, or digger cancelling another digger, and of course releasing blockers. As I'm writing this, I just realized I probably could had made the right-most entrance much easier by using the digger cancelling another digger trick. Or at least dig, block, and then dig with a left facing lemming to release the blocker.

Though I managed to solve the level, I'll be honest and that is I'm not a huge fan of this level due to how so much scrolling needs to be done, especially since it's impossible to watch all entrances depending on where you are in the level. If anything, I got extremely annoyed by the excessive scrolling that needed to be done very fast. That definitely made me dislike the level even more after I was past the initial intimidation. Because of this, a lot of pausing is needed, and it definitely makes planning the solution out that much more difficult. Looks like I echoed Icho's dislike of extremely large levels where you can't see all lemmings at once.
