All levels have a maximum of 14 lemmings, so I won't note this in individual cases. Similarly, if levels with 20 of each skill are reduced to 14 of each, I won't note this individually.From Fun 1 to Tricky 3, the music rotates between tracks 1, 3, 6 and 9 (using the Amiga numbering). Tricky 4 has track 11.
Fun1 - Just dig. Same as original.
2 - Only floaters can survive this. Same as original.
3 - Tailor-made for blockers. Mostly the same, but the 3-blocker solution doesn't work because the last drop is a splat fall.
4 - Use some miners and climbers. Same level, slightly different title
5 - You need bashers this time. Same as original.
6 - Now for blockers and bombers. Same as original.
7 - Have you tried a builder? Equivalent to "Builders will help you here", but skillset is 5-5-0-0-5-1-1-1. Ron didn't include this level even though the skillset is very different; I guess that's fair enough as the solution is pretty much the same.
8 - As long as you try your best. Similar to the original; requirement is 8/14 and skillset is 5 of each.
9 - Smile if you love lemmings. Same as original.
10 - Keep your hair on, Mr Lemming. Similar to the original; 6 of each; the top 2/5 of the wall is not one-way.
11 - Patience. Skillset is 7-7-2-2-2-2-2-2 and the gap on the other side of the central wall is very narrow.
12 - We all fall down (included in Ron's remake pack). Skillset is 14 of each!
13 - Origins and Lemmings (included). Skillset is 5 of each and there is a crack in the terrain and a rope trap.
14 - Danger, the bridge is out (included). Similar to "Don't let your eyes deceive you"; skillset is 5-5-6-6-6-6-0-0 and the middle gap can be crossed by one builder.
15 - Do not do anything too hasty (included). Similar to the original; there are small mid-air platforms above the terrain spikes.
16 - It looks very easy. This is "Easy when you know how", 5 of each, and the compression method solution is impossible because the trap breaks through the floor and kills everyone!
17 - Block and blow. Original layout; skillset is 5 of each.
18 - You live and Lem. Level is actually "This should be a doddle"!
19 - I get that lemming feeling. Truncated version of the original without the right-hand wall and hidden exit.
20 - Konbanwa Lemming-san. Similar to the original; trap is replaced with a terrain block.
21 - Lemmings lemmings everywhere (included). Similar, but the mesh terrain has gaps and the web has become a spiral.
22 - Two for Lemmington Spa. This is "Nightmare on Lem Street".
23 - Be careful out there. Similar but only gives one minute! Skillset is 6 of each and 6/10 required to save.
24 - Norra lorra lemmings. Similar, but building up the shaft to the exit is infuriatingly hard with NES controls!
25 - Lemming and Lime (included). A version of "Speed Trap" from ZX Spectrum Lemmings (Quirky 28 in Redux). The block under the trapdoor is steel, and there are zapper traps at the top of the mesh; skillset is 6 of each.
Tricky1 - This one is a doddle. Similar but skillset is 0-0-1-1-3-1-0-0 (the gap can be crossed with 2 builders).
2 - A bag of lemming drops (included). "We all fall down" with skillset 8-8-0-8-8-8-0-8. With NES physics, it is
not possible to dig partway through the platform, bash, and dig again to make a step; the solution is for some lemmings to float and others dig.
3 - A ladder would be nice. Similar but skillset is 0-0-2-2-8-0-0-0 (it takes 4 builders to get up the cliff).
4 - One I prepared earlier. Skillset is 8 of each and there is a terrain gap in between the first mountain and the one-way wall.
5 - Lemming I Scream (included). "Careless clicking costs lives" but as well as the typical gaps in the mesh terrain, there is a splat start! Fortunately only 1 lemming is required to be saved....
