I've always been a fan of the Acorn Archimedes version of the Lemmings and Oh No! More Lemmings.  The animations are super-smooth and it largely adheres to the original Amiga implementation (e.g. has only a 2-minute timer on Mayhem 15), and the music is quite good for its chipset, which is why I also like the Oh No! port on the Acorn Archimedes because it has a very wide selection of new music tracks, from the Trumpet Hornpipe (Captain Pugwash theme), British Grenadiers, the Camptown Races, Greensleeves and even Wicked 2: Inroducing [sic] SUPERLEMMING! gets a unique and very fitting track... Yakedy Sax!

Looking at your replay, You can completely remove the third bomber from the replay (Listed as 02098: Lemming #37, Bomber) and the solution still works, saving an extra lemming.  The bomber there is completely unnecessary.

How's this, MASTER-88?  Probably a backroute as I have a lot of skills left over and I'm one above the save requirement.

Ooo, how did I miss this?  I'm up for it, but I'll have to check my schedule.

Glad my pack left an impression on you!  I did what I could to try to make a smooth difficulty curve, complete with easy levels to warm you into the groove, with Cute starting around Fun/Tricky and ending at about mid-Taxing, then Curious goes into Mayhem difficulty, then Cunning starts to really up the difficulty with some unique combinations etc.  Challenge is similar to "Present" in the MegaDrive version of Lemmings in that the difficulty isn't consistent, but it tries to be a self-contained difficulty curve, starting easy and ending very difficult.  And Chaos... well, it warns you with the skull-and-crossbones icon and the warning message after you complete Challenge.  Almost every level requires some true outside-the-box thinking and clever tricks.  I like to think that Chaos 26 and Chaos 28 really inspired a few people.

I admit I do like time limits, but I try not to make them unfair, and I do try to patch backroutes that could be mistaken for the intended solution if they have very sharp timings, since I want to reduce the frustration factor where possible.

I've got Rule 1 and Rule 3 done, but Rule 2 is giving me trouble.  I had one design, but a backroute gave me trouble so I might try to redesign it a bit.

This is the version of Tier Drops from Lemmings Cranium that fixes the backroute in a similar way.

Heh, a clean sweep!  Nice one kaywhyn!

Well, the levels I posted at the start of this topic I'm hoping would be good for a Level of the Year nomination.  A new pack won't be for a while though.

Some more updates since:

Though not a turn off in themselves, I would say that levels where you're allowed or at least expected to lose a number of lemmings I find the hardest since you're not sure where you have to sacrifice them.  One example that springs to mind is "Stroke at Retirement Age" by geoo, where you are allowed to lose 4 lemmings but only have one Bomber and Blocker (and it's very obvious where you have to use the Blocker).  On top of being very precise it's very hard to know where you can and should make sacrifice.

Sometimes though, sacrifices are the name of the game, like with the aforementioned Cascade (I'm pretty sure the developers were aware of being able to save 100% or at least more than 10 because of being able to dig through the steps to make a wall, even if a few slip through into the abyss.  I myself have taken advantage of mass death in some of my own levels, my most famous probably being "Mincemeat" (go to 1:59):

That's kind of you JawaJuice.  I might still try to fix Lemming Ledger as a standalone level, but I admit I've lost faith in it, and Reverse the Polarity I'm kind of leaving to die.

Quote from: mobius on December 06, 2025, 12:59:58 AMwow, that was 10 days ago I posted? It felt like yeserday... well I skimmed over the topic quickly and I don't think you've updated these two in that time??
I solved these two with the help of SQRon, The Oubliette particularly was very tough imo, but very clever solution, if it's correct. Outside the box is likely a backroute, I saved the blocker, but it felt as least partially intended, the overall jist anyway; I don't see how else to go about it... this solution does not work for the second one.

I patched The Oubliette, but let's just say you're very close to what I intended, so the patch should now enforce it.

In the meantime, I've added a copy of Backdraft to the second post of this topic for easy finding later on (where all the other levels are!)

Backdraft is intended - well done!  Now I wish I did submit that to the contest instead of Lemming Ledger despite the similiarities to Redneck Redemption.  The talisman does take a fair bit of thought!

Speaking of Lemming Ledger, both that and Double Blind are backroutes, but well done on using all of the tools!  I think they can be patched, but I'll take a day or two to think about them.
