Thanks for the replays, IchoTolot.  About half of them are pretty much the intended solution.  The other half are a mix of alternate solutions and backroutes.  I'll probably have an updated pack later this week.

Congratulations! Your pizza is indeed the biggest, but it is also too far overcooked to eat.

I wish I had a full head of hair.

Terrain changes along the bottom.
Added walkers, reduced skill counts to 2 each.
Increased save to 18/20, dropped RR to 1.

I can support option 2 or 3 for the new editor.  Right now I am leaning toward option 2.  I have absolutely no problem for the 2.0 editor being just for NeoLemmix levels.

My biggest concern about option 3 is how all the metadata would be managed in a fullscreen mode.  (I assume that NeoLemmix 2.0 will be fullscreen like its predecessors.)  Right now I let the Inspector, Skillset, and Level Properties windows float off to the right of the main editor window so I can have a full height view of the level I am working on and still be able to see critical metadata simultaneously.

If you do decide to support file association, I suggest using a more distinct suffix for level packs, like '.leml' (lemmings level) or '.lemp' (lemmings pack), rather than the current '.dat' and '.lvl' suffix.  '.dat' and '.lvl' are used by so many different programs now - enough that I don't want to make a file association for those (unless it is something like a generic text editor).

I'm the current Quizmaster and how I made the latest round of questions was this - I started with the resistor color code sequence and did some word associations, then for most of the colors I made questions that matched the word I came up with.

My original list went like this: black=the pirate Blackbeard, brown=bear, red=Little Red Riding Hood, orange=carrot, yellow=road sign, green=pine tree, blue=pants, purple=???, grey=hair, white=wolf (specifically the nickname 'White Wolf' for Geralt from The Witcher series), gold=jewelry, silver=superconductor metal.  Purple was the only color I did not have a good association, so I stuck the flag question there.

I don't think that a text screen introducing every new skill is necessary.  The eight levels focusing on each specific skill do a better job introducing the skills - showing as opposed to telling.

The only thing I would change about Fixed Ascent is to add some more space between the wall that the first basher needs to go through and the first up ramp, probably simpler to to move the up ramp to the left.

When the fade glitch occurs, it seems to happen every 4 or 5 levels while playing for a while.  I thought level length could be a cause but I have seen it pop up after short levels with a couple of skill assignments or after a long level with many tasks.

But I can just start up a game and hit F3 and page back and forth between the two settings panels and the glitch seems to crop up once every 5 times I switch between the two pages.

I'm getting the same error.

Also, there is a very simple backroute to the new disarmer level - make the first lemming the disarmer and wait.
