Hi Mobiethian!

Congrats on your new level pack, these levels are incredible!

I managed to complete every level, although I think some of my solutions for the later levels may be backroutes (see attached replays)

Spoiler

The 'Prepare' rank was quite easy and very enjoyable, the levels are beautifully decorated and often reminded me of levels from the original lemmings game. As an added challenge, I tried to save 100% on each of these levels, which was also very fun.

My favourites from this rank are probably "Tree Trunk Labyrinth", "A Sacred Vault", "Down in the Root Cellar", "A Little Flower Walk", and "Valley of the Mushrooms". The latter three especially were quite fun since they were quite tricky to save every Lemming. I also really like the designs of "Construction Function", "The Steel City" and "Caught in Liminal Space".



I found the 'Nuisance' rank to be much harder, some of the later levels really got me thinking. My favourite is "The Chosen One". I think it's really great level to end out on due to its high difficulty. Solving this one felt really rewarding, since it forces you to think critically and piece together the solution based on the odd skill selection and save requirement. "Mesmerizing", "Hoppin' On the Groove Line", "In the Rear with the Gear", "Glow in the Dark Pool" "Deep Chasm of Coinage" and "Terrarium" were also really fun, although I wasn't able to get the talisman for the latter.

By far the hardest for me was "Mirror World", it took me hours to solve, and I'm fairly certain my solution is a backroute, but I'm at a loss for ideas on how to proceed otherwise. "Down the Rabbit Hole" was also a really tricky level that I think I backrouted.

Also, just FYI, in the level "When the Whistles Blow" the steam on the far right side of the level doesn't kill the lemmings - it needs to be 1 pixel lower so they don't walk under it.

Overall, this pack was really fun to play through and I feel honoured that it uses my tilesets. Thank you so much!

Thanks so much for the feedback and for playing through my levels, I really appreciate it and hope it wasn't too annoying. I'll definitely a look at how I can improve some of the levels you mentioned, I might implement a lot of these suggestions which are really helpful, I already had a go at fixing a couple of annoying gaps and making some more obvious.

The title says it all. Currently, when you have autosave replays enabled for RetroLemmini, the replay that is generated uses the  following filename naming scheme:

Level Pack Name_rank name_level number_Level name_time stamp_date

Yea, autosaved RetroLemmini replays generated this way are way too long IMO. Often times, a lot of the replay filename won't be displayed and hence you would need to mouse over it and/or right-click the file and click Properties.

So, my suggestion would be to provide some other naming schemes when an autosave replay is generated in addition to the one that's currently used for the feature. For example, in NL the level pack folder is made with an Auto folder inside it where the replay resides. In particular, I use NL's autosave rank and level number for my replays. I would certainly use this same naming scheme for RetroLemmini autosave replays if there is such an option  

Hello @hrb264,

I have cleared all of your RetroLemmini pack My replays are attached

General Feedback

This 40-level pack is a first attempt by newcomer to the Lemmings Forums hrb264, though she has some experience from having played and completed Lemmings, Oh No! More Lemmings, and Holiday Lemmings. In particular, I believe she has mentioned that she grew up playing the Win95 version of Lemmings. There's at least a few others in this community who have played the Win95 version as well, including WillLem.

This pack contains 5 ranks of 8 levels each. The Skills Refresher rank are essentially skill tutorial levels similar to what the first 7 levels of the Fun rank of Lemmings 1 did. The rest of the pack just have the 4 ranks of L1 as the rank name. At least for the first two ranks, hrb264's goal here was to make an easy pack to pretty much serve as training for her nephew when he eventually plays through the game himself. Here, she attempts to make levels where you only need to know the basic function of the skills in order to pass them. For this reason, my suggestion here is to first have him play through at least Lemmings 1 in order to get an idea of how the game works first before having him play your pack. Having him go through ONML after finishing Lemmings isn't a bad idea as well The reason I suggest this is because custom level packs are often times much harder than anything the official Lemmings games throw at the player. Hence, playing through both L1 and ONML allows the player to get an idea of how the game works, even though they won't necessarily make him or her well-equipped to handle the hardest packs available. However, because hrb264 has tried to intentionally make levels where getting through them mostly just has skills do their basic function in the early ranks, this pack should still be fine for your nephew

Overall, because of how very open-ended the levels are due to giving a lot of skills available, there aren't any levels that are very challenging, even in both the Taxing and Mayhem ranks, the penultimate and final rank, respectively. Here, I'll probably say that Mayhem 4 is the hardest level of the entire pack. Everything else is either quite easy or, IMO, annoying to play because of being level types that I personally am not a fan of or possibly the kind that tends to be frowned by the Lemmings community. In particular, I personally am not a huge fan of levels where you need to repeatedly assign the same skill over and over, especially if it's in a short amount of time. Here, the worst offender in the entire pack IMO would probably have to be Mayhem 7. I nearly skipped the level upon seeing it because of all the huge gaps that you need to build across that span the entire level and 4 entrances you need to watch and that requires a lot of annoying scrolling or jumping around the map.

For the latter level designs, there are some of those, such as hidden exits. To soften the blow, hrb264 is well aware of these questionable level designs since she has read the "immediate turn-offs" topic on the Forums. They just happen to be the type that she likes. In this pack, they aren't too bad, as at least hrb264 gives far more skills than you need in order to find them. These aren't as bad as levels with hidden traps, though most in this community tend to consider both types not good level design. This is especially true for the latter, as solutions that would had worked now don't because of a hidden trap that one couldn't see ahead of time. Thus, if the designer hides the exit or trap, that's why people suggest putting some kind of visual indicator, such as an X, to mark where the exit or trap is. Because these levels tend to be frowned upon by the community, it's likely many people won't play such levels, especially on an engine like RetroLemmini, where there's no rewinding and hence one screw-up and the player is forced to restart the entire level, similar to playing the game on the original engines like win95 and Dos.

Overall, while a lot of the later levels aren't the type that I like, in particular ones where you have to repeatedly assign the same skill many times, this is still a decent first attempt at a level pack by hrb264 There is plenty of room for improvement, as there are some issues with many of the levels, but most of these are easily fixable. For example, I've encountered a lot of annoying one-pixel gaps which are very difficult to spot just by looking at the level due to the colors masking them very well. hrb264 has already mentioned to me that some are intentional, but some might have arisen due to possibly the game not rendering the levels correctly even though the level editor doesn't show the gaps. I don't know if that's what's going on, as I haven't taken a look myself or used the RetroLemmini level editor. Similarly, Taxing 1 looks to be a huge visual mess in the Sega style, but hrb264 has mentioned that she'll be tidying that up in a future update

Another would be fixing levels to remove dependency on the level edges due to how the behavior is very inconsistent depending on what engine one is playing on. For example, in RetroLemmini, all level edges are safe except for the bottom of course, but in New Formats NL, all level boundaries are deadly. I personally don't like to use the level boundaries when solving levels, and same with making levels.

Finally, to me, a lot of the later levels felt quite dragged out and almost like they served absolutely no purpose on being big and long for the sake of being big or long. Thus, consider whether the same level can be done on a much smaller map. At the same time, there's also a lot of one-screeners, but for some reason a lot of these felt too cramped. Really small levels are not a problem in terms of completion time, as they tend to be super quick. They just felt like there wasn't really any room to move around at all.

Fun Rank Feedback

All pretty much easy levels due to having way more skills than you need to solve them, along with very lenient save requirements. It was pretty fun challenging myself to go for save all's on as many of these as I could

Spoiler

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 Rank Feedback

Levels are a bit harder here but still quite easy.

Spoiler

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 Rank Feedback

Pretty much the levels start getting quite challenging, but these are still much easier than the Taxing levels of L1.

Spoiler

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 Rank Feedback

Despite being the final rank of the pack, these levels aren't too difficult for the most part save for Mayhem 4, which IMO is the hardest level of the entire pack, with Mayhem 2 a really close second.

Spoiler

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.       

Thank you for the pack hrb264. As mentioned, a decent first attempt at making a pack, with plenty of room for improvement on making levels less annoying and not as excessive on repeatedly assigning the same skill, but I always like seeing what people are able to come up with with the levels they make So, I certainly look forward to more levels from you which will hopefully be a lot better in the future! In any case, we're glad to have you here with us be part of a wonderful community of this excellent and iconic game that is Lemmings!    

Thank you for kaywhyn for taking time for the Kid Lemmings pack.

We had fun watching your solutions, and it turns out kids are like me : they dont like when people solve their levels not the way they imagined 

Thanks also for pointing out the different music issues. I tried to turn on the volume on the Dragosta Din Tei track and modified the other levels with custom musics that may not be present on anyone installation of NL. Now the standard rotation will play most of the time. The new .zip file includes everything that's needed to play with correct music, hopefully. Just unzip in main NL folder.

I must say that one should maybe not expect the kids to create more levels in the future. As often with children turning their attention quickly from things, they are now bored of the Lemmings game and think about other things when it comes to video game, Fortnite for instance ! Nightmare, I dont let them play this yet.

And when it comes to the one still inside the lady's womb, please let her live (yes it's a girl !) without using screens for many years, and then more time to grow up before touching a computer. Please expect levels from her, if any, not before 2040 A.D. We'll be old by then, but the Lemmings game will still live.

Quote from: Guigui on March 03, 2026, 05:07:10 PMThanks for the clarification about custom sound FX.

As for custom music, I encounter an issue where I download HQ Music.rar file but then I cannot unrar it. I think this has to do with my Linux system that does not handle .rar files correctly.

Anyone kind enough to compress the music in another format like .zip for me to be able to access it ?

Hey Guigui  You can just install p7zip for Linux for free - that can extract RAR files.

Quote from: IchoTolot on March 03, 2026, 03:38:36 PMFirst, congratulations on the release! 

I have one question regarding the downloads:
Are the custom sound effects optional and overwrite the standard ones? 
If they are indeed replacements for the standard ones I would place a hint in the first post to backup the files you going to overwrite so you have the option to switch back.

Thanks IchoTolot I would suggest this and I let Guigui know as well a little while ago. Perhaps a player can make a backup copy of the original sounds - if you wish to use the custom sounds. Then overwrite them from the backup when you need the originals back. I hope that makes sense. I usually have a copy of NeoLemmix in each level pack. It's a habit and it works great. I hope this helps!

In answer to your question about it being optional, it is. They don't need to be used at all actually.

First, congratulations on the release!

Firstly, congratulations on your release, @Mobiethian - it's a very nice pack! Thanks for allowing me to playtest I won't attach all of my replays as you've seen most of them already, but I did find that you'd updated a couple of levels in the Nuisance rank to the point where my previous replays no longer worked; namely When the Whistles Blow and The Aquatic Ruins. I'll attach replays for my new solutions to these levels. On the latter, gotta say great job to you and @kaywhyn - this is an excellent level, one of my favourites of the pack, actually! Cutting down on the number of builders has made it really quite tricky. To my mind, the hardest level of the pack though is @Armani's The Chosen One, another favourite of mine as it showcases a couple of neat mechanisms/tricks that I hadn't seen before. Overall, a very nice-looking pack (great use of some lovely tilesets), with a ton of enjoyable challenges. Look forward to your next one!
