Dayum... nice backroute!  Patched it because I don't like unfair precision and it isn't what I was after.  The intended gold talisman solution is pretty clean.

Very strange. I'm not currently at my laptop so I can't test this immediately. Has anyone with a Windows machine noticed this?

Best guess is that it's something to do with hotkey priority, I'll take a look at it soon.

I personally like the colour cycling, but can see why it may be annoying or counterintuitive to some users. Settings could allow users to specify a colour using a hex code, I'll look into this soon.

Outline wouldn't be the best idea for water and/or OWWs because in both cases the trigger area affects whatever it overlaps, including any added terrain.

The idea of CPM is to make it clear where the triggers are, pixel by pixel. Outlining is at best asking the player to work it out instead of just showing it, and at worst could even render some trigger areas invisible (if the outline is outside the terrain piece, for example.

I'm typing this on my phone, I'll come back and add some visual examples later.

As for the colour, I see no reason not to allow users to specify whatever colour they like. I'll look into whether this is feasible.

Monster Munch resolved again. The 3:30 talisman wasn't a problem, but the <= 12 skills one was very hard to figure out and took me a really long time. There were plenty of things I've tried that would had worked but ultimately most use 13 skills or fail because of pixels with too high step ups. In the end, the <= 12 skills talisman also satisfies the time attack talisman, and again I'm not sure if you intend for both to be obtainable in the same solution. If the latter one is acceptable, I'm quite curious what you intended for that one! At least in my solution, it needs a lot of precision!

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

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.

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.
