This was a lot of fun. At first I was very daunted by the level because I'm not well adjusted to the new stuff. But after a little playing it actually became a lot simpler than I thought. Watching the others' replays made me realize a lot of simple things I overlooked.

I admit there were a couple of things about the level which annoyed me, but on  a whole I liked it actually, and felt well suited to this challenge.

One of the annoying things was the worker being a glider; this seemed to be nothing more than a nuisance and never actually helpful. The other thing was what to do about the exit area and how to clear out the zombies (or prevent them from going in there quickly, which is what I did but found out in the end not necessary). This was in part due to zombie hit detection being quite unforgiving in some circumstances imo.

Will we still be able to edit the colors ourselves the same way as before (in theme.nxtm)?

I think to really lucid dream (control it and have it last) takes a lot of practice. That is; you must do it many times before gaining this 'ability'.

As I've said before the few times I was aware during sleep is so bizarre its often shocking and thus I wake up. So it takes getting used to.

For whatever reason this is how our brains work; some part is constantly churning up information (images, words etc) from our memory into our consciousness and there is often no obvious rhyme or reason for it. During sleep/dream its more extreme because other parts of the brain are dormant. Like the parts that organize thoughts in respect to attention and memory and other things, respond to outside stimulus or which normally preserves memory. This is why dreams are chaotic and why most people don't remember most of their dreams.

its' been 10 years and I still occasionally have dreams about being late for school or class. But then highschool was not a good time for me.
I wouldn't worry too much about what your dreams mean actually; a wise man said to me; 'It don't mean a thing... what's real is what's going on here and now..."

edit: That's not to say there's nothing to be gained my discussing them. I still love discussing them of course; mainly for entertainment. When dreams are not scary and pleasant it's like free natural entertainment for your brain while resting. And at times they do point out things that you might not have realized are going on in your real life, but a lot of the time, I think its easy to read too much into them.

I plan to do an LP of the game at some point in the future (likely after LPing Keiran's L2 pack, so some months from now at least). Idk if I'll do the original game or Kieran's pack. (probably Kieran's pack)

This Saturday (two days from now) I plan to stream Super Mario Maker 2 at or around 17:30 UTC. Let me know on discord if you can make it/plan to watch or have any requests or what have you. I may stream other things as well depending on how SMM2 goes.

The moving spike/saw trap is much more complicated than that:

Firstly; its quite different from weasels or zombies because it doesn't follow the rules of them (it doesn't need to walk on ground) and they can move in different directions; vertical, horizontal or diagonal. (for example one level featured them moving in a 10 or so degree slope direction, super fast in a big zig-zag pattern). And they can move at different speeds; much slower to much faster than lemmings. And they can be turned on or off (made to stop moving or start) with switches. And they can cut through terrain even! And they can do your laundry!
Just for arguments sake I do find them puzzle-friendly. Though I'm not certain if the game had any really good examples. "It's going to take time" might be though. There's a saw moving around near the exit and you must get the group to go through at a good time and doing so isn't simple; that level is actually quite the skill crunch. Swarthy Sea Dogs was also fun when I solved it the first time, but not sure how good of an example it is for this though.

Break-away floors exist in only three levels in the game: Speedy Gonzolas, T is for Teamwork, Which Switch is Which? This apparently existed in L3 as well but I've never seen it.

There were also 'time doors' which was a gate with a number counter by it and after a certain number of lemmings passed the gate closes. It could sometimes be opened again however with a switch (And the counter reset)

The Gates, believe it or not, imo were one of the best used features in the game. Unfortunately many examples I can think of are levels that suffer from other problems that will make people turn away. But I think the principle is pretty sound. There are quite a few levels in the game that make decent use of them imo. They can keep weasels in, lock lemmings in, or let them to danger, or kill weasels or lemmings (by closing on them as you mentioned). Off hand I think "Turn on Tune in Switch on" or "Just you wait" is the best example of them; The former being a really cool concept and my favorite level.

A much simpler mechanic that was used to very good effect in the game was having different types of lemmings that needed to go to specific exits. There was regular, water and acid lemmings. The latter two which of course had other interesting properties; water lemmings could walk on water and that was used in conjunction with draining pools a lot. You can kind of achieve this effect (to a point) in present NL by using pre-assigned skill hatches and places exists in specific places only reachable by athletes of certain types.

Graham's number

Let’s have some fun with really big numbers.
Suppose you took the four vertices of a square. It may be obvious but important that we're dealing with two dimensions so it has four vertices (2^2). Draw lines connecting all possible pairs of every vertex; you'll find there are 6 in total (four on the 'outside' and two diagonals).

Now you can draw each of the 6 lines one of two colors (red or blue in my example). And there are a bunch of different combinations you can have there. You could draw many of these square representing each combination. See example A.

So what? Well there are some interesting configurations you could create... but not with this square; we need more dimensions. A three dimensional cube has 8 vertices. And now there are 28 possible line segments. Now color each line one of two colors same as before.

The whole point of this exercise is to avoid the following configuration:
A square (contained somewhere within this cube) with all 6 vertices the same color. See example B.

In three dimensions (a cube) it is possible to avoid this. Is it avoidable in larger dimensions? There is the 'four dimensional cube' or a Tesseract. See the below picture (Which I believe is correct but keep in mind only a representation). Here there are 120 different line connections. How many different ways can you color these?

A simple calculation but a not so simple answer: 2^120= 1,329,227,995,784,915,872,903,807,060,280,344,576

Already a number that's difficult to express by computers. To put this number into perspective here's a list of some 'ordinary numbers'

one thousand = 1,000
one million = 1,000,000
billion = 1,000,000,000
trillion = 1,000,000,000,000
quadrillion = 1,000,000,000,000,000
quintillion = 1,000,000,000,000,000,000
sextillion = 1,000,000,000,000,000,000,000
septillion = 1,000,000,000,000,000,000,000,000
octillion = 1,000,000,000,000,000,000,000,000,000

Astronomers by the way, estimate the number of stars in the known universe is around 70 sextiliion...
The above number is larger than all of these. But back to the problem; the question is can you avoid a flat (in a plane) square of all connected vertices with the same color within the tesseract? The answer is yes. It is known that it's avoidable in fact in 5 dimensions, all the way up to 12. So is it always avoidable?
The answer is no.
If the dimension is large enough you cannot avoid this configuration.

Let's take 13 dimensions. In a 13 dimensional cube you'd have 8192 vertices.
8192*8191/2 = 33,550,336 line segments. So possible configurations of red/blue lines in this example would be 2 to the power of 33,550,336... A number that most computers cannot compute. The answer to 13 is not presently known. But the point at which it must happen that it cannot be avoided, that is, the upper bound, is known; Graham's number.

How big is Graham's number? It's pretty big. So big that a different type of notation must be used to help describe it. Arrow notation describes powers of powers. Here’s how it works:

3↑3 means 3 to the 3rd power (3 cubed) = 27
3↑↑3 means 3 to the power of three, to the power of three (in other words 3 to the 27 power) = 7,625,597,484,987. Every new arrow adds another exponent on top of the exponent, a tower of exponents so to speak.

So what is 3↑↑↑3? Simple; we already know two arrows mean 7 trillion, so this means 3 to the power of 7 trillion. What number is that? Well the answer contains 3.6 trillion digits. So I can’t write it here. There is no specific name for this number or any numbers in this realm for that matter. This kind of number cannot even be written accurately in scientific notation (x*10^n). Already this is a number that is not really comprehendible by humans because we have no point of reference for such numbers. We’re used to dealing with single and double digits in our lives. We may even struggle with mere triple digits. And 3↑↑↑3 isn’t even close to the realm of Graham’s number.

Now take 3↑↑↑↑3. Once again we can skip steps because we already know that this essentially means 3 to the power of ((3↑↑↑3)a 3.6 trillion digit number). So this number has many, many, many times more digits than the previous 3.6 trillion digit number. For every single arrow added to this operation it puts you in a whole other world of size so to speak. And every arrow raises it by a degree far greater than the previous increase. And still, we’re not even in the ballpark of Graham’s number.

3↑↑↑↑3 represents the number of arrows in between another pair of threes. This gives you another number of even greater earth shattering epicenes. Remember just 3↑↑↑3 is a number that cannot be written down. The number we’re looking at is gotten to by doing an operation of 3 followed by a number of arrows equal to (3↑↑↑↑3) So; insane orders of magnitude greater than 3↑↑↑↑3. This is by the way far greater than a googol or a googolplex.

The answer to that then gives you another ridiculous number. This then is the number of arrows to use in the next step, between another pair of threes. Repeat this process 64 times. This is Graham’s number.

This number is so large that (based on current knowledge) there is not room in the finite universe to store the number via digital data nor time in the universe’s lifetime to write it out. In other words there are more particles in the known universe than digits in this number.

Amazingly while most of the actual digits are unknown the last several are (…….195387); because any power of three’s final digits are very predictable.

Even getting to Graham’s number is mind-boggling. Of course it’s nothing compared to infinity. But that’s a topic for another entry. What’s your favorite gigantic number?
