Random Lemmings Plus DOS Project Trivia- In a voteoff between all levels of LPDOS, the best level was voted to be Medi 6 "Fallen".
> > This level was then pitted against the LPII winner, Genius 8 "Panic Attack". At the time of writing this that vote has not yet closed, but Panic Attack is winning by a large margin.
- The name "Lemmings Plus DOS Project" was originally just a codename while the pack was in development. Due to lack of any better ideas, it stuck. The sequel packs also had codenames prior to an official name being chosen, those being "Lemmings Plus 5 Project" for LPII and "Lemmings Plus X Project" for LPIII. (LPIIB was always called "Lemmings Plus II Bonus Pack" from the beginning of development.)
- The first level in LP DOS to be made ever was Danger 11 "The Warp Room". It is in fact my oldest surviving DOS level, and possibly my oldest surviving level full stop (I'm not sure which is older - it or "Dialing 309 2000" from Lemmings Plus 1).
> > This other contender was remade for LP DOS but is not immediately recognizable from its source. The remake is Danger 22 "Die the Death of the Damned".
- The first level in LP DOS to be made specifically for it (other than remakes),
as far as I remember, was the No Salvations - specifically, the Psycho 29 rendition of it "No Salvation V".
> > This original form of Psycho 29 was almost identical to the one present now. The only differences were 50 lemmings (required 98%), and the title was simply "No Salvation" - it had this title in the original release, in fact all the No Salvations were titled simply "No Salvation" until version 4.
- The first remade level from the Cheapo Lemming Pluses ever was, as far as I remember, Danger 14 "Death In All Directions".
> > "Death In All Directions" was in fact not originally a Lemmings Plus level. It originally came from my an entry in my side series, "Ultimate Challenge 2". This level was however re-used in Lemmings Plus 2; and remade for Jihoon's Lemmings Remake then reused in LP DOS.
- The first remade level specifically for LP DOS was, as far as I remember, Psycho 28 "To The End!".
- Every difficulty rank except Psycho has a level which gives you 20 of every skill. Psycho itself still has a level that gives you 20 of all but one skill.
- The highest total skills given to you in one level is 320, in Medi 11 "The Long Road To Lemming High". Prior to V7, it was 336 in Wimpy 12 "Life the Universe and Everything".
- There are two levels which do not give you any skills.
- On each difficulty rank, for each skill there is at least one level that has none of that skill.
- Prior to V7, there was a major Hitchhiker's Guide to the Galaxy reference - Wimpy 12 "Life the Universe and Everything". Apart from the name, the level also had 42 lemmings, required 42%, gave you 42 minutes, had 42 of each skill and a release rate of 42. And - it was the 42nd level in the pack.
> > V7 removed this level but coincidentally snuck in a new reference. At the time of releasing it, I knew how many levels were (or were thought to be) impossible to 100% for each rank, but I never bothered to total them up. Had I done so, it would have come to 43. Very recently, I discovered a 100% solution to one of these levels (Psycho 22 "Twins"), thus meaning V7 has 42 levels where 100% is impossible (as far as I'm aware).
>> Due to Akseli finding a 100% solution to Medi 18, this is no longer true.
- The "key" level (I guess you could define this as like the level that I would promote as the key selling point if I were advertising it?) from each of the Cheapo Lemmings Plus packs were all remade for LP DOS - LP1's "Return of the T", LP2's "Lemmerixo" and LP3's "To The End!" (Psycho 18, Psycho 14 and Psycho 28 respectively). The last of these three was itself can be seen as being the key level of LPDOS as well, though due to it being a remake, some might prefer to consider No Time To Die the key level instead (technically NTTD is also a remake, but the pack it was from was never released so LPDOS is the first public version of it).
- Psycho has only one level that does not give you any builders.
> > However, it has two other levels that give you builders, but they would not be used in most solutions.
- Prior to V7, Mild 18 "Dying Not Reccomended" had a repeat at Danger 21, titled "Phase Rotation Syndrome". This level still exists in the datafiles.
> > Due to this replacement, Mild 18 is the only level which uses oddtable but does not have a repeat nor is a repeat itself.
- I personally consider the 5 hardest levels to be (from hardest) Psycho 28 "To The End!", Psycho 27 "No Time To Die (Part II)", Danger 22 "Die the Death of the Damned", Psycho 20 "No Time To Die", and Medi 16 "The Oddstack".
- The zapper traps in the crystal and bubble sets are the only triggered traps which are never used in LP DOS.
- The shortest gap between a level and its repeat is 10 levels, between Mild 26 "No Salvation I" and Wimpy 7 "No Salvation II". If you exclude No Salvations, it's 14 levels, between Danger 27 "The Deadly Climb" and Psycho 12 "Not gonna work.".
- The longest gap between a level and its repeat is 126 levels, between Mild 4 "In The Style Of..." and Psycho 11 "Three Birds With One Stone". (This even beats No Salvation I and No Salvation V's seperation.)
- Every first level of a difficulty rank either has a repeat or is one. This is also true for the last levels of Wimpy, Medi and Danger, but not for those of Mild or Psycho, which both finish with a unique level.
- The most you're ever given of a single skill is 50. There are two levels which have both 50 bombers and 50 blockers (Wimpy 25 "Down With The Lemmings" and Medi 5 "Safety Blast") and one level which has 50 builders (Wimpy 24 "Up, Down, Round & Round").
- Danger 24 "Find A Way Out" originally was going to have a repeat at Psycho 23, titled "The Framework", but it was overly plagued by backroutes. Ironically, the level that became Psycho 23 "Death Row" has suffered the same fate anyway.
- I'm not sure how I didn't notice it at the time, but Mild 15 is
extremely similar to Fun 15 from the original lemmings.
- Two difficulty ranks have the same number of levels that require 100% as they do of levels where it is impossible to get 100% - Mild (with 1 of each) and Danger (with 11 of each).
> > Danger, in fact, has more levels that require 100% than Psycho does.
- Of all the first and final levels of ranks, the final level of Mild is the only one to use an ONML graphic set.
- Only two of the final 10 levels require 100% - Psycho 27 "No Time To Die (Part II)" and Psycho 28 "To The End!".
> > Two others of them are possible to acheive 100% on but do not require it - Psycho 22 "Twins" and Psycho 29 "No Salvation V".
- Mild 20 "Stairway To Infinity" and its repeat Medi 6 "Fallen" have undergone multiple name changes and aesthetic redesigns since the first release of LP DOS. However, the level has never been backrouted and the design of all functional pieces has never been changed; all changes were purely cosmetic.
> > The original name of Mild 20 was "25909", I don't remember the original name of Medi 6.
- There are only two times in the entire pack where there are three levels in a row with the same graphic set. These are Mild 19-21 and Medi 10-12, with fire and brick respectively.
- PSYCHO 11 and PSYCHO 28 share the same music (as is normal for levels 11 and 28 of any rank) and graphic set. Their easier versions also share the same music as each other, being levels 4 and 21 in their respective ranks.
- The number of lemmings (53) in Mild 25 and its repeat PSYCHO 15 does not have any significance or hidden meaning; it was chosen completely randomly, just to break the monotony of always having a "normal" amount of lemmings. Generally, other levels with odd numbers of lemmings have a reason for it (for example, Danger 18).
