Bonus 1 : So many difficult part in this level that I have no idea where to start :
*) compress to go the middle way with the crowd ? But I have no idea how to compress without loosing to many skills and lems, and I still have the issue of that bottom teleporter that will kill one more...
*) let the crowd use the upper teleporter ? Cannot do that either yet, getting there with the crowd uses a builder which I have to use elsewhere.
*) what about those pickups ? The top one is a builder, and I need to use a builder to get it, so nothing won here. Well actually I can win a climber in the process, but I dont know what to do with it...

Bonus 2. What I have to do is quite clear : forge a path for both the swimmer and sliders to reach the exit. I have decided that swimmers have to go right part, and sliders left part (maybe I'm wrong ?). But then my main difficulties are :
*) very beginning : I'd like to separate sliders and swimmers here but the only way I find to do this already uses 3 builders and 1 stacker. Too much for the rest of the level
*) avoid the splat on the right part with the swimmers. This uses so many builders that I am stuck after.
*) ending part where I have to turn the sliders around. Doable with a stacker, but then the swimmers cannot go to their own exit.

Bonus 4. Counting the gaps, I see that the skillset is one platformer short. So I need to set the stoner in the middle of the 2-platforms-long gap, and to clone the platformer here, great idea (hope I get it right).
I see where/how I have to set the stoner and how to reach it with a glider. But my issue is that to achieve this I need 2 swimmers, which means I need to use the cloner earlier, so no cloner left... Cannot overcome that.

Bonus 5. Does not seem so hard at first sight, but if I set the climber too early the I use too much ressources to avoid him dying at those climb=death part. I need that climber at both the beginning and at the end of the level, so no idea how to do that.
Also I cannot see how to use the bottom part of the level. Once I'm stuck in here, I have no idea how to get out since I have no destructive skill left...

Bonus 6. Not tried yet.

1 - Crying Over Spilt Lemmings

Nice level to start with. The Lemmings from the upper platform have to be caught with a bridge.

2 - Entanglement

This one is all about finding the correct way around the steel blocks. Since there is only one miner and digger each, this is not trivial - but no big problem as well.

3 - Square One

One-of-everything-level. A climber has to be isolated who paves the way for the crowd. Still an easy one.

4 - Fight Fire with Fire

Only one of the three hatches requires attention in the beginning. The solution is pretty straightforward, so this level is a bit time-consuming, but, again, fairly simple.

5 - Give the Lemming His Due

Another case of catching the crowd with a bridge. The time-limit is pretty tight here.

6 - Groundhog Day

The name says it all. It's again about isolating a climber who prepares the way for the rest. Still, not a bad level, albeit a very easy one.

7 - Lem Overboard!

A little step up in terms of difficulty. It's clear that those from the left side have to be saved from those from the right side. So the first Lemming from the right hatch has to hurry up a bit. The rest of the level was no problem although I had to watch out that the bridges don't run out.

8 - Swing for the Fences

Back to easy. Again, a climber must be brought into action who - in this case - constructs a long bridge the crowd can finally land on.

9 - The Acid Test

Actually no problem as well. However, I think the time-limit can be a critical factor here. Also, the bridges should not be wasted, there are not excessive amounts available.

10 - Sacrificial Lems

Nice puzzle. Two of the three climbers can not be saved, so the title makes sense. The time-limit is unnecessary here. But I like the crocodile on the left side.

11 - The Boardwalk

The best level so far and definitely a challenge. The obvious way is not possible since too many lose their lives in the traps.

12 - Down The Upside

I overcomplicated things here. Thought I had to block on the upper floor instead at the bottom. But this way, I only managed to save seven. Good level!

13 - Cream of the Crop

Very messy solution that does not look intended at all. Did not use any of the five bashers, so this must be a backroute.

14 - The Dugout

While not being overly difficult, I really like the concept of this level. Nice to see how the final Lems save those at the bottom of the pits.

15 - Stuck in a Rut

Not much of a problem here again. Trapping the levels at the bottom gives the pioneer enough time to complete the bridge.

16 - Lemmings on the High Ground

Not quite as easy as it looks, due to the absence of blockers and especially climbers.

17 - Trifecta

Very easy level. The only challenge might be bringing the climber over to the left side.

18 - Kessel Mineshaft

A lot of work to do here. I needed all the builders and miners here, so I think, this is how it's supposed to be.

19 - Out on a Lem

Good level. Took me a while to see that I had to use the basher's tunnel to turn around the other two climbers. I definitely overcomplicated this level before.

20 - Deus Ex Lemina

Looks harder than it is. Those between the steel blocks can and must all be made climbers. I saved the builder here.

21 - High Rise Lemmings

Nice turn here to save the final basher - the one that releases the blocker - through the other exit. Took me a bit to see this. 

22 - Rapid Descent

Another good one. My solution is probably not quite the intended though - as I spared a miner.

23 - Separation Anxiety

I can remember a level with the same concept in another level pack - so I could grasp the key idea right from the beginning. From this point, it wasn't a hard one. While mining through the block underneath the entrance, the Lemmings have to be counted, though. Only 15 are allowed to fall down left of the trap. 14 will become climbers then, one has to block. The 15th climber is needed for the right side.

24 - Keep Your Lems Close...

This is a very appropriate named level. The time-limit ist extremely justified here as it's the core of the puzzle. I placed a blocker beneath the second hatch (from left) and built a bridge over it from the right side - so that the Lemmings from the left two entrances wouldn't walk further to the right. It was still tight in the end.
