Enjoying life is difficult at the moment, but thanks!  Hanging in there is hard.  In the meantime, backroute alert.  V6 released.

R1's are V1.

Changelog History of R2:

V2 - Increased height of steel veins to patch a backroute from Velixi. Added more decorative veins.
V3 - Extended length of steel veins to the left of the sphincter(!) to patch a backroute from Kaywhyn.
V4 - Moved leftmost tooth to patch a backroute from Kaywhyn.
V5 - Returned to V3 as a base to reintroduce backroute, but made it slightly more difficult to pull off.  Bronze talisman time reduced from 3:45 to 3:30, and new gold talisman to complete using only 12 skills.  Some other minor terrain changes.
V6 - Changed shape of leftmost hill to patch backroute from Kaywhyn.

Changelog History of R3:

V2 - Small modification to the terrain at the waterline to patch a backroute from IchoTolot.
V3 - Extra entrails and blood drips underneath the platform to patch a backroute from IchoTolot.
V4 - Lengthened an entrail above the skull to patch a backroute from Velixi.

Monster Munch resolved once more. Got both talismans in one go. Not sure if this is intended or acceptable, though. Thank you for the clarification on Discord, because I honestly fail to see how you came up with the thought that I don't think highly of your R2. Quite the contrary! I think it's a fine level itself! So, relax, smile, and enjoy life

In Lemmings 95, if playing on Windows XP SP3 (or just on my specific XP device, not really sure), vertical lines will randomly start being drawn if level tiles are coming from the right side.
Compatibility mode does nothing here, not sure how else I could fix it 

I still think that this is important. I don't build NL levels; if others see potential problems with these ideas (outline instead of filled pink rectangle), please bring up those problems.

It's conceivable to draw the areas of only some gadgets as outline. When a gadget affects terrain (e.g., one-way arrows), you can, e.g., fully fill the matching terrain, and not paint the air. The important fix will be that huge water areas don't generate huge pink blobs that are hard on the eyes.

I'd like to prod WillLem to consider this. People activate these helper tools when they need to know the details, therefore you want maximally clear helpers.

CE 1.0.1
NL 12.14

Clear Physics Mode shows the silhouettes of all gadgets in rotating colors. There is a global timer, and the color of the silhouettes is that timer modulo N in the circle of fully-saturated colors (red, orange, yellow, ..., cyan, pink, red).

Enough with that! I use Clear Physics Mode when details matter, and I don't want this distracting color clashing.

In 1.0.1 Clear Physics Mode, lemmings are dark-blue (0, 0, FF). Instead, make lemmings medium-blue (80, 80, FF). That's easier to see than dark blue (this alone will be an improvement!) and it will remain sufficiently different from the cyan athletes (0, FF, FF).

Now you can make gadgets dark green (0, 80, 0) and you won't step on any toes.

Pick other colors than what I propose, I'm happy to try other choices.

CE 1.0.1
NL 12.14 and other versions from years ago.
Wine 10.6

• Start a level.
• If it's a small level, zoom in until you can scroll.
• Scroll with the hold-to-scroll feature. E.g., map this to the right mouse button in NL's options, then scroll by holding the right mouse button.
• While you hold-to-scroll, press a skill hotkey to select a different skill.

Observed: You have a ~50 % chance to select the new skill. Otherwise, the skill key has no effect and the old skill remains selected. (The hold-to-scroll will always continue to scroll correctly, whether the new skill selects or not.)

Expected instead: The new skill gets selected for certain. (And the hold-to-scroll will always continue to scroll.)

Post the glitches you discovered in other versions of Lemmings. For example; a builder with his air backpack and his bricks in the 3DO version.

Small update, the person who made the Crash toy was not involved in the production of the Lemmings toy... That unfortunately means pretty much all points of contact I have are exhausted.
I'll keep my ears out, but I don't have a ton of hope. If anyone finds this thread in the future and wants to contact me, my discord username is: metalgearsolid2_sonsofliberty

Mostly intended - I just swap the last basher and miner.  I'm too emotionally compromised to really do much more right now.

Well, after spending a couple of days trying to recover and realise both routes have potential, I've hopefully found a good compromise in V5 of Monster Munch.
