Oh Yeah More Lemmings by MASTER-88 (100 levels) D: Medium/Grand Master UP 25.7.26

[IchoTolot]

Yes your solution is not intented, but is sure accetable and impossible to patch so congrats about it.

Oh, then I misunderstood you, but still glad to see that it is acceptable. 

As you already mentioned it I attached my soltion to level 9.

1.01 Version started are ready. I´ll look out every solutions once yet.

I´ll later post all fixed things under spoiler tags. Step 3 seems contains most backroutes entire pack, though all those not was very bad ones. Technically few levels was totally broken my 1.00 version. Step 1 Level 19 and Step 5 Level 3. Also Step 4 Level 13 walking on hot coal was pretty broken too.

And its look Step 5 Level 3 Lethal Sidewalk finally work correct, added new toolsets and some improve objects. That was some hard level to fix.

I´ll back later when public my 1.01 version.

Probably my final post re OYML. I have solutions for a few more levels in the final 'Havoc Highway' rank, plus an extra 'save all' solution for the final level.
So overall this leaves me with 8 out of 100 OYML levels I have not managed to solve on my own, 4 in the 4th rank 'Wicked Webroad':
 level 4_06 Agoraphobia
 level 4_08 Lemmings Are Grounded
 level 4_14 Methods Of Masters - MASTER88 says this is a relatively straightforward level, and the required strategy does seem obvious, I just can't execute it successfully
 level 4_16 There is No Time To Waste
and 4 in the final rank:
 level 5_09 Fiery Cells - solved by IchoTolot with a solution different to that intended, but I can't see how anything substantially different could work
 level 5_10 I Am MT - a Digger-fest, but with other challenges beyond me
 level 5_15 Scorching Terminal - again, solved by IchoTolot with a solution different to that intended, see my comments under the Spoiler tag
 level 5_19 Decimation - I have a solution but it draws on others' work.

Havoc Highway levels 12,15,16,19,20

Level 12 "Offerings Could Save Others": I delayed taking a close look at this level, for fear that it might be a miniature version of level 10's Digger-fest. But actually it presents a much more interesting challenge. In particular it needs some tricky choreography near the exit, where 3 different activities need to be synchronised.
Level 15 "Scorching Terminal": it becomes clear that: (a) the advance lemmings have to take the low road; (b) the crowd have to take the high road. The problem is that each road ideally needs a Cloner, but only 1 Cloner is available. For (a) the required path is relatively easy to see but executing this without using excessive skills or the Cloner is very difficult. The intended solution apparently requires 2 special tricks, and I know the one involving the Cloner, but not the other one so I fall 1 short of the Save requirement.
Level 16 "Gloomy Night": the hairtrigger chameleon traps, triggering every 5 frames, make it enormously difficult to meet the save requirement. It becomes clear that evading 2 of the 5 traps on the obvious route to the exit will not be enough, even with a tightly packed crowd. At least 1 of the 2 traps nearest the trapdoor needs to be bypassed completely. With no Diggers or Miners, the only way to bypass from above is with a Platformer - otherwise a way is needed to use Bashers or Fencers acting from below. For a long time my best efforts, using Glider-Shimmier to get the advance lemming over the gap on the right, and platforming above 1 of these 2 traps, still left me 2 short. There is a route that bypasses both the near-trapdoor traps and gets the required number to near the exit, but with no way of accessing the exit. So I looked for a 'from below' approach using the Shimmier in a more conventional way. This took me to a solution which, in all its key components, is the same as IchoTolot's. This approach succeeds only if the crowd are released in exactly the right way - I got lucky at the first attempt, then failed in my next 4 attempts to recreate the approach.
Level 19 "Decimation": trial runs show that, within the time limit, it is impossible to save the final 8 or so lemmings via the right-hand exit, using the conventional route; and that they cannot be saved via the left exit unless an advance lemming clears the way first. I cannot claim much, if any, credit for my solution, as it draws on the first 5 seconds of IchoTolot's solution and the use of the Miner in MASTER88's 'Common Mistakes' YouTube video showing unsuccessful solutions.
Level 20 "Havoc Highway": my additional solution saves all 103 lemmings. Inevitably this takes a bit longer than just meeting the Save requirement, and needs a few more skills; but there are still 6 skills and over 6 minutes to spare.

Revised set of solutions for the final rank are attached. My thanks again to MASTER88 for the brainteasers.

Nice Job Plodderuk your progress my pack. 1.01 Version is finally ready. I´ll post with this post and my main post.

Several Backroutes are patched and some new talismans added (There is a lot talismans in Step 1) But no much other difficult.

I´ll post New Differences my main post and under spoiler tags.

[MASTER-88]

BTW I was really want Patch some backroutes few those Step 5 Levels. But i simply cannot make it. How ever those levels seems just super hard even backroutes used. So i´ll have to allow those backroutes my 1.01 version. That most reason, because my intention solution contains some super special advance tricks, which are really hard figured out and very rare used any packs.

I´ll list few levels. Which allow you use alternate route, because i cannot patch those ones.

Some Secret Reveal

Step 5 Level 9 Fiery Cells. My solution is very unique and contains very rare trick, but i have to allow IchoTolot alternate solution, which is also very genius, but still clearly backroute.

Step 5 Level 15 Scorching Terminal. My solution contains few super advance tricks, but i cannot patch those ones, so you can beat this level in future just at least two very different ways, used my route or IchoTolot route, both is very genius ones.

Step 5 Level 18 Stairways to heaven, very rare trick i used my intention solution is impossible to forced used. Plodderuk did very nice alternate solution and i´ll keep it, its less complicated than my own one, but much intention elements is still here and there.

Good Luck to 1.01 Version my pack. Its improvement a lot   Have to say Oh Yeah More Lemmings is sure my best pack i ever maded. Its very complicated and very retro style. Expect theme levels. There is no buttons, pick up things. Its just pure retro lemmings skills. Backroutes will be allowed if i cannot fix those used normal ways.
