Instead of building on top of the tree on Calm 6, I now just need to have the Lemming drop down to the steel and then start building up to the egg. Tense 4 also fails for this same reason as my worker doesn't build on top of the tree, but that's ok, it's not that big of a deal for me to manually recreate my initial solution for the level

Calm rank

The Stumbling Block Sorry I did not try to save as many as I could here, just let my luck go and saved enough.

The needs of the few I had a hard time containing the crowd here, and ended up doing it under the chameleon. Certainly not optimal but it worked.

A Slight Detour It is worth noting that I played the pack backward : Panic->Tense->Calm. Dont ask me why, I just dont know. Maybe I like to end with easier levels.
In any case, this was consequently the 3rd time I solved this level, and with supposedly the easiest skillset. Remembering the other detour solutions, I thought "enough with the detour, this level title is just teasing me". So I just brute-forced my way to the exit, sorry 

Status Quo I love the design of this one, buccolic (is that an English word?) walk under the rain.
I love how that precise raindrop makes crossing the pond with builders painful : bridges end right in the raindrop, then you are forced to go up and splat !
Once again I just said "to hell with it" and went the whole bottom route. Sorry again 

Your Egg Is Cracking Once again the 3rd time I saw this level, playing backward. I tried my best to save 100% here but did not manage to save the 6th lemming from the splat at the beginning, my builder is some frame short no matter what I do. Anyone could save 100% here ?
I must also applaud the egg design, it fits very nicely in the Oh No Rock original style and this is a serious feat.

The Lemming Hair Dryer A level for the girls ! Love the electrical design, I could 100% with the upper route.

Follow Me! I found this one hard for its rank. At first I tried the upper route but did not have enough constructive skills. Turns out the bottom route works : building the many gaps actually allows to spread the lemmings apart and makes the final timing quite lenient.

Break The Cycle I recently quite fully understood the power of the so called "Dolly Dimple" bridge which allows to separate a worker from the crowd with bridges only. Applied it here and end up with an extra builder at the end.




Tense rank

Lucky Brick 3rd repeat of this level for me. Sorry I just cleared all of them with mostly the same technique each time. This is what happens when you start with the hardest one : you cannot unsee the solution you had the previous times.

Going Down I love this one ! The bridge technique I used here is also similar to a possible solution in the ONML Dolly Dimple level, which is one of my favorite level of all time considering how much time I spent stuck on it in the 90's.

Meet In The Middle Good level, my favorite of the 3 repeats, and among the favorites in this pack.
I had trouble with this one, again my fault because I was trying to more or less reproduce the solution I had for the Panic repeat of this level! It did not work though, and I scratched my head for a long time ... until I realized the level name gives the solution! 
How dumb of me not to see it, when I actually did the same in the Save One pack : give clues on how to solve in the level name!

Wait For Me! I must say I did not understand this one. The save requirement of 1 lemming out of the 2 is weird ? I just let one lemming die in the water and saved the other with the many skills available.
No idea how to save both though.

Panic rank

Lemming-Lime Soda Very good level, among my favorites in the pack!
I used one builder at the beginning to allow the pioneer to dive in the water and avoid splat. Then I went the bottom route to free the crowd. Pioneer died though, RIP.

Freezer Burn Mean level, poor Lemmings die after about 5 frames of living. I had a hard time getting to save them, and just enough builders to do so. I'd say my solution is not optimal, but it works.

The Serpent Biggest roadblock to me. I spend much time figuring out how to get up there, the compression solution did not occur quickly! After that and the idea of half turning in the serpent's eye, things were not that easy because one has to place the miners very carefully to be able to save the crowd and reach the exit.

Lemmings Replacement Theory Tough repeat of Calm 2. At first I though it was simple, until the first miner fell right before the central block, and all subsequent lemmings with him, of course!
I kind of quickly understood that the 2 losses would be 2 miners going to the left, the hardest part was to manage a half turn with a lem to the right of the central block.

Be The Girl You Wanna Be No real difficulty in the buccolic sunny grass. I may have once again forced things with basher + builder cancel thing.

Cave-Divers Builderless level, you know how to please kaywhyn.
Love how you have to use the ascending terrains to their full extent here. Also dont waste the destructive skill, because a quick count when you finally get to the upper floor may show that you dont have enough.
I was a bit frustrated that one cannot do 100% here though (or have I missed it : how to half turn w/o the blocker on the right side ?). Also some skill assignement are very precise.

A Death-Defying Stunt Tremendous level 
Many possibilies here but also many of them that do not work, so I had to experiment a lot. The way to save the 2 blockers was quite obvious, but it used a lot of builders. So one has to be extra careful with the other parts of the level that have to be done almost w/o builders. Special kudos to the way you neutralize the bottom left trap right before the exit, this one took me much time to figure out.

As kaywhyn said though, I'd also point out that if one puts the left blocker a bit too far to the left on the beginning platform, he may not see that several shimmier can be escaped from the crowd. When you think about it, those shimmier going over the blocker when they are so close to it are pretty counter-intuitive. Maybe just shifts the shimmiable curved piece a bit to the left, so that even if one puts the blocker at the very left edge of the starting platform, then shimmiers can still be escaped ?

The Four Horsemen Of The Apocalypse Nice level to end the pack.
I could see a solution, though it was hard to set up correctly : over the exit, I had to make a digger pit with 2 lems in it. When the digging is done, I could make one lem walk to the right toward the other lems waiting to be saved, and the other walk to the left to the exit.
This was pixel/frame precise, and quite fiddly to pull out. So I think this solution is not the intended.
