Just like that, you're in the home stretch and down to the final 5 levels of the pack. If I'm not mistaken, the level you're currently on was the one that stumped me the longest out of all the other levels in the pack. If it's not 16, for sure it's the next one, 17. Indeed, despite being a 1 of everything level AND a 1 minute level, Tricky Quicky is very aptly named! Similar to It's Hero Time from the original lemmings, 1 of everything AND also 1 minute.

If it is 16, this all reminds me of the situation I was in about 2 weeks ago: down to the final 5 levels of the main part of United, with the first one of the bunch supposedly the hardest level of the entire pack. I ended up solving it earlier in the week, and TBT I didn't think it was THAT hard. Then again, I do have a skill leftover and so it might be a backroute. Now, almost a year after I first started playing the pack, I'm on the final level of the main pack (I still have the Bonus rank to do). I have yet to make any serious attempts at it, but let's see how long it will stump me.

Let's motivate one another to finish the pack we're currently playing through. You can do this! Besides Tricky Quicky, once I got past that, unless the Superlemmini levels got replaced with new levels for the NL version, I recall the remaining levels weren't super difficult.   

Ok, I saw your replay and it fails by about 3-4 seconds. This is interesting, as that was not the first thing I thought up of. I know you also mentioned that you had one that failed by about a second, and I'm guessing that one was more or less the same as the replay you attached with the positioning of the skills altered a bit. Once you read the hint, you should be able to totally solve it now.

Hint for Hellish 11

If the bottom route takes too long, then it should be clear that you must take the ...

To save a replay, just press U at any time while you're still in the level. This is different from replays that are saved automatically when you are successful in passing a level. For this one, you have to make sure that is enabled via settings in the main menu. I presume that you do have that enabled, since replays through that are saved by the rank followed by the level number in the name. Replays via the U key are saved in the exact same naming format, although the location where these are saved are different. Instead of being inside the Auto folder (these are the ones that are automatically saved when you pass a level) that is inside the level pack's name, these replays are simply saved inside the level pack's folder. In any case, you get to the replays by going into the replay folder, followed by the level pack's folder.

I still wish I knew what you're doing that's running out of time. In any case, I already said that I found two solutions, both of which solve the level within the two minute time limit, although one leaves about 5 seconds remaining without nuking.

I did mention that "there's many packs for Superlemmini." The packs I mentioned were ones I remembered off the top of my head and ones I feel are good for any player to begin with, especially if the person is new or is rusty. My intention wasn't to list every pack available for Superlemmini (too many to list). Also, you kind of already had it covered when you mentioned for him to look under the "levels for other engines" and Superlemmini board, so any packs I didn't mention he could just look in those two places anyway.

Since Reverse Lemmings is simply the original game with the entrances and exits swapped and given how you already completed the original game, this pack shouldn't be a problem for you at all. However, feel free to ask for a replay if you're stuck on a level. Like I said, though, I think you'll be fine. Also, the pack was recently converted to NL, but it seems no one has completed it yet.

Be aware that custom level packs are generally more difficult than the official games. However, if you're willing to look into playing custom level packs, especially with eric's remakes and conversions to Superlemmini, I recommend beginning with Dovelems. It has a really nice difficulty curve from start to finish, and is generally easy throughout, although there's still a few real nailbiters, especially in the later ranks. It was the very first custom level pack I played when I found out about Lemmini.

I can also recommend Dodochacalo's other mini packs too: Franlems, Dodopack, and Cachapack. The former is a pack of 40 levels entirely in French (I believe eric translated it all to English when he converted the pack to Superlemmini), while the latter packs are each 10 levels (20 levels total). These 3 packs are more difficult than his Dovelems pack, but they should still be manageable. Pimolems is another well done pack that's slightly harder than Dovelems, although I say the real difficulty starts at the third rank and stays high until the end of the 4th rank. The remaining ranks are special ranks and a bonus rank.

Then, if you're still willing to tackle even more packs and looking for a real challenge, Reunion is a highly regarded pack that has a nice difficulty curve throughout that's considerably harder than all the packs I mentioned in the previous paragraphs. The pack gets difficult much faster than the original game does. It already starts getting difficult near the end of the first rank. After the other packs I mentioned, this was and still is the largest custom pack I have ever completed, at a total of 150 levels. Also, all the packs I mentioned, including Reunion, I first completed on Lemmini. Reunion took me about 3 months to complete. Definitely not for the faint of heart or for the easily frustrated, but if you're willing to take on the pack, it's readily available for download.

These are all just suggestions, of course. You're more than welcome to start with the harder packs first, but if it's been a really long time since you last played Lemmings (I don't know your history, so I don't know how long it's been since you last played the game or if you have played any custom level packs), I would definitely start with the official games (Lemmings, ONML, Holiday Lemmings, etc) first, followed by Dovelems if you want to play custom level packs. Even without brushing up on the official games first, I say that it's still viable to start with Dovelems, as it does ease you into the game again with tutorial levels for the 8 classic skills, followed by easy puzzles.

I've played and completed all of the packs I mentioned, so that's why I'm able to offer my views on the difficulty of each. In any case, there's so many level packs to play and enjoy that it'll take a long time to get through them all. What's more, more are being made all the time, both from the veteran players and new, so the amount of content continues to grow all the time.   

Glad to be of assistance. Enjoy revisiting the game with the many packs available for the engine!

Hey Dr. Boogang,

The reason the extraction is failing is because you also need a copy of the Winlem files. Both Lemmini and Superlemmini require these files in order to run. You can download a copy here: https://www.lemmingsforums.net/index.php?topic=2101.0. It's the 3rd link where it says Lemmings for Windows. Extract the files somewhere on your computer. Then, when you run the Superlemmini.jar file, when it asks where the source is, that's where you want to navigate to where you extracted the Lemmings for Windows files.

Here's my replay for the bee level. I didn't think it was that hard, but I can see why it can be hard, though. My solution almost fails and I have a spare builder. Let's just say that my entire solution was practically all self-inflicted pixel precision, especially with both miners.

also in dodo's cachapack level 9 Mesa Amarilla there was this quirk to where a lemming can build thru a thin strip and continue past. so when I recreated this level for both NL and Superlemmini,
I had to fix it to be a similiar solution.

Yes, building through a 1 pixel wall but still continuing is also a glitch exclusive to Lemmini. Does not work in NL and Superlemmini as you saw, and so the level had to be fixed. I believe in Lemmini backward bashing (confirmed to work) through a wall works, just like in Superlemmini. Does not work in NL.

Here, this is what I mean by backwards bashing. This of course is Retro 20 in the OP. This might work as an alternative solution in lieu of the original glitch solution which doesn't work. Solvable with just a bomber and 2 bashers and the OWW on the thin wall. That's because a basher's mask slightly extends behind him as well, and hence they can bash through a wall backwards, although not much. This also applies to backward mining.

Very nice! Alternatively, I think a single flamethrower trap can work too.

edit: Keep those fire pits there. It turns out that without them, you can simply use the bashers to backward bash (i.e, assign a basher to a lemming the instant he turns around) on the thin wall.

edit 2: Actually, this could be an interesting solution. The original Retro 20 with just a bomber and two bashers with the OWW on the thin wall. It's not as interesting as using a blocker to push them through the thin wall, but this one is still somewhat interesting, using a quirk of the basher skill on a OWW.

Reply #260 from here, and I quote just the second to last item here. Apparently I missed that completely the first time I downloaded the newest Superlemmini version. Good to know that before I read through the thread again that it was somewhat verified through testing that it doesn't work anymore and then to find the actual verification.

After too long, SuperLemmini 0.104 is finally out! Here is the rather large list of changes:

• Blockers and one-way objects no longer push lemmings through walls.

Thus, since the original Retro 20 relied on this glitch, this change therefore renders the level unsolvable. Basically, the solution was bomb somewhere on the starting platform, then build in such a way that there's only 1 pixel between the stairs and the thin wall, and block in a certain position close to the wall so that it "pushes" the others through it. Not block so close to the wall that the lemmings will just hit the wall and pass through the blocker from the right. Thus, the positions of the builder and blocker are quite precise.

However, I did have a look at your version of Retro 20. Interesting solution, but see my replay. Just 3 skills and done!

I grew up with the Dos version of Lemmings, and so I knew about horizontal movement with diggers and builders. As you can see, that's the only way through the flame/ice blower area, especially if you want to save 100%. And yes, you're right about just building a spiral staircase for the exit area. As I mentioned, mine is just one of many, many ways to do the level. Now that you have your own replay for Hellish 20, you can now add it to your zip file in the OP and reattach.

Luckily, Sublems is already available for Superlemmini. As for the NL version, a lot of the Superlemmini levels got replaced with new ones, either because they were unpopular or Arty wasn't able to convert the Superlemmini level to NL and hence replaced the level. So, be aware that some of the Superlemmini levels aren't present in the NL pack.

Allow me to provide the replay you're missing. Here you go, my 100% Hellish 20 replay solution. I had another one, but I found out, to my chagrin, that my replay didn't save at all. So, take note: DO NOT USE A COLON IN THE NAME OF THE REPLAY! Because of that, I had to do the level all over again.

Just one of the many many ways to do this level since you have 99 of everything. Also, as to why certain areas were avoided, just look at the level in NL and you'll see how there's so many hidden traps that you can't even see in Superlemmini. Watch the very end and you'll see how extremely annoying it is. The part just before the exit area is physics from Dos that allows you to do that with the diggers and builders. That works in NL too. The solution also relies on how sides are solid in Superlemmini. Of course, you could do more of the repeated bashing and cancelling midstroke with builders to get even higher and get to the exit so you don't have to bounce off the side of the level, but this is easier.

Now have fun doing it yourself. Just remember: lots and lots of framestepping for the very end!

eric: Is the replay working for you?
