Hey. Bit late (since I hardly ever come here), but just want to say that you're more than welcome to include any of my levels if you like. I don't have a recent copy of Lemmings Plus DOS Project (does anyone still have a copy of the most recent version, I can only find broken links? EDIT: Nevermind, I found it!), but the majority of levels are unchanged from the versions on the file archive (the only one that's changed *and* notable is Coalburner).
I'd suggest To The End!, Hellfire and No Time To Die (part 1, not part 2) for potential inclusion. Pipeline Problem as well, perhaps, for a slightly lower difficulty one.
EDIT: I found a working copy of the latest version of the project! w00t!
So here's a list of levels I feel are particularly good:
- "Up To Where They Go" (Mild 19) - this is quite an easy level, but it's very fun nonetheless, might be good for Fun-equivalent
- "You Just Lost The Game!" (Mild 30) - same as above, though this would be late-Fun, maybe even early Tricky
- "Russian Rescue" (Wimpy 12*) - This is a low-to-mid difficulty one, probably worthy of Tricky or even *very* early Taxing
- "Fallen" (Medi 6) - Mostly a simple puzzle, but the 100% requirement puts a bit of extra difficulty on it, maybe early-to-mid Taxing
- "As It Burns Away..." (Medi 21*) - Moderate-to-high difficulty, late Taxing-y
- "Lemmingsense" (Medi 29) - Another mid-to-late Taxing one
- "Backdraft" (Danger 3) - Not one of my personal favorites, but it seems to be quite a favorite among other players. Probably early Mayhem difficulty. (Note that this level relies a bit on precisely-placed bombers. LPDOS is modified so that bombers instantly OhNo when you assign them rather than count down; so this level could be quite annoying if you're using the older-style timed bombers.)
- "Alternative Logic" (Danger 6) - Simple but with a clever trick to it. Note that this level doesn't work properly in all versions of the game (varies between game and even between settings for DOS, won't work on Mac, works fine in Lemmix under *any* mechanics setting) due to the level being EXTREMELY precisely adjusted to the time limit.
- "Circular Wavelength" (Danger 15) - Another Mayhemish puzzle.
- "No Salvation IV" (Danger 20) - The earlier No Salvations are too easy, the later one too hard. This one offers a good challenge while still giving some room for variety.
- "Die the Death of the Damned" (Danger 22) - This one is very challenging to work out (but very simple to execute once you know how it's done). As far as I'm aware, only one level in both original and OhNo combined use the mechanic that's required here. Definitely at least late-Mayhem.
- "Pipeline Problem" (Danger 29) - This one's a bit easier than most of those around it, though don't let the simple look and 10-of-everything decieve you; it IS a fairly challenging level. Probably late-Taxing.
- "Variety Day" (Psycho 1) - A one-of-each-skill level! =D I've had mixed responses on how hard this one is, I'd say probably early-to-mid Mayhem.
- "Coalburner" (Psycho 9**) - This is one of those ones that can be quite tricky to work out, but once you know it, isn't that hard to pull off. I'd say late-Mayhem.
- "Three Birds With One Stone" (Psycho 11) - This is a level with several solutions, all of which are fairly difficult to find (some are hard to execute, others are quite easy). Late-Taxing or early-Mayhem.
- "Not gonna work." (Psycho 12) - Another level that looks simple but isn't. This is easily far harder than anything in Mayhem; it's debatable whether some of the ONML levels surpass it. It actually originally was an early-Medi level with a lower required % and had blockers; I thought "I wonder if I can save 100%" and after how much of a challenge that was, it didn't take me long to decide "I'm bumping this one up to Psycho and requiring 100%".
- "Return of the T" (Psycho 18) - Apart from being qutie challenging (definitely late-Mayhem if not harder), this level deserves to be nominated simply for being (in it's first incarnation, as a Cheapo level in Lemmings Plus 1) the first genuinely hard level I ever made - anything before that was a matter of "easy to work out, hard to execute", if hard at all.
- "No Time To Die" (Psycho 20) - A fun and quick level. Can seem like an annoyingly-tight-on-time level at first, but once you work out what you should be doing, there's actually a suprising amount of time to spare - not huge amounts, but a good 10-15 seconds or so. Nonetheless, it's definitely post-Mayhem.
- "To The End!" (Psycho 28) - Probably the hardest level in LP DOS, and at any rate it seems to be one of the favorites of mine among most people who've played it. It starts with the pretty common "make a fairly easy, and long but still fairly fun level with 20 of each skill". It then slaps a 100% requirement on that (out of 30 lemmings, so not everyone can climb/float) - not a huge deal. It then applies a twist that wasn't so common in the PC version, but fairly common in the SMS version - instead of 20 of *every* skill, you have 20 of most skills but there's one you have none of. And then comes the catch - instead of something only moderately useful like floaters, the skill you're missing is builders. In a level full of large drops, edges you need to turn around at (and remember, it's 100%, so blockers won't do much for you), and so on. Good freakin' luck. =P Difficulty? I'd say this level is well harder than anything found in even ONML.
- "Hellfire!" (Psycho 30) - Well, with the unfortunate placement just a couple of levels behind To The End, this level doesn't seem quite as hard as it actually is. It's a pretty fun and challenging level, I'd say it's post-Mayhem though not even close to TTE's difficulty.
* "Russian Rescue" and "As It Burns Away..." were new additions to Version 7, older versions had "Life, the Universe and Everything" and "Ghostly Hall" in these positions instead. (Four other levels were also replaced - Medi 8, Medi 16, Danger 21 and Psycho 27, but none of these other replacements are, IMO, worth nominating. Of course, if other people feel differently, I'm happy for almost any level in this pack to be included.)
** "Coalburner" had some minor modifications - that resulted in an ENTIRELY new solution - as of Version 5. Obviously, I'm nominating the new version (though the old version was pretty fun in itself).
If you want to include any of these, let me know and I'll see what I can do about extracting them from the compiled player. (It *is* possible, I just have to remember *how*.)
I would've liked to nominate Death Row as well, but unfortunately, that level's freaking cursed... no matter what fixes I apply to it, either backroutes don't truly end up fixed, or new ones pop up. Therefore, I don't really think it's fit for inclusion (and as such, I'd rather you didn't include that one - any *other* level is fine to include). At any rate I've long since given up on that one (and plus, V7 is the absolute final version of LPDOS).
