You're welcome!

Even if you re-solve these design problems, it will be worthwhile to see your solutions. You have different constraints than the existing games. And you may well find a solution that blows everything out of the water, and we should all copy it.

For example: Lix and NeoLemmix have savestating frameworks for fast rewinding. That's for manual rewinding to undo a mistake, or for history editing, or to allow the multiplayer mode to react to delayed packets. Maybe you'll decide upfront that you don't need savestating. Your design choices for error prevention must now make sense in a world that can only ever go forward. Compared to Lix/NeoLemmix, this will be a new design restriction. Looking forward to your solutions!

I'll come back to the smileys this Monday, May 25th.

Then you might be interested in my recent LPs, as I've done a complete LP of L1, ONML, and Holiday Lemmings 1994, all for the Amiga. I made sure to point out the differences between the Amiga and Dos versions of the levels if I remembered to

As for Genesis Present and Sunsoft ranks, as far as I'm aware, no, no one has yet done a Reverse Edition of those ranks/levels. So, feel free to make your own take of such a pack concept for them! I also recently did a live stream of the entire port, including showcasing the 2-Player levels!  

Im not are check out this channel in few weeks. Is Step 4 goes too hard?

If you need some help about tricks or etc.. I´ll answer. Step 4 & 5 contains some unique stuffs all around.

Step 4 is still much easier overall. Step 5 is just Pure hell.   Its contains maybe most hardest lemmings levels you can ever imagine. 

Wish luck if anyone could beat this pack. Im not are make 1.01 version yet. I´ll work it. Its will at least patch few backroutes steps 1-3 and add some new talismans.

Thanks for the explanation kaywhyn, I was not even aware of the differences between DOS and AMIGA version of the game.

Can you confirm that the Present and Sunsoft ranks in the Genesis version of the game have not been reversed by previous people here ? If so, I'd like to work on that if time allows.

Yeah, to be clear I'm not saying it should be changed, but I noticed it happening a few times now and it was interfering with a solution i tried for the level (although I worked out how to complete the level without this)

Lemmings also get trapped at the ceiling not only in Retrolemmini, but also SuperlemminiToo

@Guigui

You didn't link to the topic for the Class Edition Reverse Lemmings pack properly, but that one is by WillLem and is for the most part identical to Colorful Arty's NL pack, except he uses the Amiga version of the levels instead of the Dos ones like Colorful Arty does. Meaning, a lot of the levels that lack the water across the bottom on Dos will be present in WillLem's pack because it's there on the Amiga version. However, Colorful Arty's New Formats NL version is pretty much a remastering of his Old Formats and SuperLemmini version of the packs and hence can be thought of as an entirely new pack even though all the levels are the same in them. It's also a completely separate pack from WillLem's version even though they both contain the same levels.

TLDR: Playing through both of them are worth the time!

@Guigui

Congratulations on clearing the pack! Indeed, as mentioned the Bonus levels were originally in both the Retro and Avant-Garde ranks and are simply the 3 hardest levels from those ranks. I was one of the pre-testers for this pack, as were Niesch and joshescue. From what I remember, I was able to clear both ranks save for one level in the Avant-Garde rank (Avant-Garde 10 from what it sounds like based on your feedback) before Armani released the pack. Same thing with the Bonus levels, but that was more I didn't get a chance to play them much as I was busy with my Lemmings World Tour LP at the time IIRC.

The hardest Bonus rank levels for me were Bonus 1 and 2, with the latter I really made a miss of the solution

Regarding Bonus 6, nice to know one of my contest levels that you played and solved earlier this year helped you with this one!

As for another pack to play, I highly suggest and recommend WillLem's Lemminas and its sequel Lemminas 2. Both are on the easy/medium side for the most part, with the latter intended to be easier and also the smaller pack of the two.     

After playing through and thoroughly enjoying Lemmings Migration a few years ago, I thought it was time to revisit Destination! This pack represents a significant step up in difficulty from Migration and the last time I attempted it (probably a year or so ago), I gave up about half way through the Argon rank but this time around, I stuck with it and managed to complete the pack. It's taken the best part of a week, on and off, but I got there!

Not gonna post detailed feedback because Nessy doesn't seem to be active any more, but I will just say I really like Nessy's approach to level design. Almost without exception, these levels are about hard problem-solving and not pixel-perfect, precise execution, 99 RR headaches or crazy time limits. So very much my bag!

Having now finished the pack, I would say that the first half of the Radon rank is about on a par with Xenon in terms of difficulty, but from Radon 11 onwards, things definitely reach a new level. Synthetic (assorted Contest levels) doesn't really offer much respite and is about as hard as the Radon rank I would say.

Lots of really clever design here, so it's challenging to pick out favourites; there're just so many great brain-teasers throughout the last three ranks, all of which have relatively long solve times. I will pick out what I thought were the hardest levels though:

Xenon 2 (Megablast... sorry, Snow Patrol)
Xenon 10 (Time For A Factory Reset)
Radon 3 (The Hanger)
Radon 11 (Wanderlust)
Radon 19 (Eulogy Of Surrealism)
Synthetic 6 (How To Self-Destruct A Factory)
Synthetic 10 (Built To Rule The World)

Basically, the entirety of Radon 11 - 20 were really tough, but the ones above took several visits to finally crack!

Just on Radon 19...

Spoiler

Reading kaywhyn's feedback, I think we both hit on the exact same method of uber fiddly basher and blocker manipulation, but I just couldn't see any other way of doing it. Also watched Icho's replay and yeah, I gotta be honest, I never would have thought of that in a month of Lemming Sundays! If that's the intended solution, and I guess it is, it just never would have occurred to me. I'll have to stow it away in the bag of tricks... a last minute nuke where one blocker frees the blocker above that relies on nuke timing mechanics. I've seen such a thing done with a regular bomber before, but not a nuke.

Probably quite a few backroutes, but my replays attached.
