Awesome project
I'm watching the Redux video now and I'll write some responses to your thoughts as I go along. I think it's really important for a pack to make a good first impression by getting its easy rank right, so it's great to have this kind of in-depth look at what goes into making a good first rank.
ericderkovits commented that he would prefer each level to have its original music. While that is just one person's opinion, I will definitely raise the question in the Redux topic to see whether others agree with this.
At the very beginning, when we were still brainstorming wild ideas, I suggested we could go for a completely repeats-free pack by replacing Fun 2, 4 and 7 with Tame levels modified to be tutorial levels for the same skills. No-one liked the idea and we quickly dropped it. In any case, we ended up keeping a small number of repeat pairs outside the tutorial levels.
"A task for bombers" isn't the first level that's been edited (we've already seen removed time limits and reduced lemming counts) but the first one with a major difference
We considered (and rejected) removing the decorative terrain on "Snuggle up to a lemming". Clearly, we made the right call
The Gentle 9 talisman should display as "Save 20 with only builders", and Gentle 16 should display as "Save 50 with 2 of each skill", so there's a bug if this no longer works. I'll look into this.
Nice demonstration of multiple solutions on "Downwardly Mobile Lemmings"
And nice demonstration on "CindyLand" that 7 of each skill is still plenty for massively overcomplicating a level
We didn't shorten "A beast of a level"; we took the version of the level from Genesis Lemmings, where it
is shorter (because Genesis levels have a maximum size of 511 x 160; this is also why, other than the special levels, levels larger than this were replaced with completely new levels in the Genesis version).
The device you referred to in "Careless clicking costs lives" is called a Newton's Cradle.
