Hi tan x,
having finished "Integral Lemmings" today, I want to write down some notes. First thing I want to say is, it's a magnificent pack. Almost all of the levels are of a high standard and absolutely well-thought. I didn't see many differences in terms of difficulty throughout the ranks, though. I like "Delta" and "Epsilon" a bit better than "Alpha", but that's mainly because I prefer the original eight skills over the new ones.
Some thoughts about the individual levels:
Epsilon:Unconventional Techniques: It's always a good thing when a level pack starts with an outstanding level and this here surely is one. Maybe it's even the best level of the rank. The key trick is well-hidden and, at least in my opinion, can not be bypassed - which makes the level even better. To be honest, while doing this level, I didnt think that I could ever solve the pack.
What Lems beneath: Also a hard one. I tried to build from the bottom but it didn't come to a good end. Not sure if the bomber in the middle is needed there, but if so, it's an amazing little trick.
A different kind of problem: I agree with Icho here - this exits here are obstacles and goals in one which is a great idea. For me, this was the hardest level in the epsilon rank. For a long time, I was always one builder short.
Send only the finest Lemmings: This level reminded me a little of "Circular Wavelength" from Lemmings Plus I. It's fun to play though not on the very hard side. Most difficult part is the beginning. Overall, one of my favourites.
Precission engineered Lemming: I knew immediately what do here, so that only the execution was the problem, especially with the hatch at the right side. Having solved the level, I looked what Icho and Kaywhyn had done here, and that's when I realised that my solution is probably a backroute.
Round the bend: A breather for many, that's why you moved it back to position 3. For me, this level was not THAT easy.
Don't forget the builders... Probably my least favourite level of the rank. Having played so many levels pack, I've seen everything here too often. Which does not mean it's a bad level. I see big problems here for novice players (but they wouldn't even reach this level)
Tarry not!: Another favourite of mine and a real time-cruncher. Took me a while to bring things in the right order here.
What have we learned so far: A fantastic closer of the first rank. Surprisingly it was a quick solve for me. Figuring out the left side was hardest for me. A very good level title, too!
Delta:Entrapment: Entirely trick based. Stunned me at first, but when I found out what to do with the stoner, the rest was a walk in the park.
Panic room: One of the best. Many different solution, but none of these is trivial to figure out - although this level looks so simple. This is really great art.
Any suggestions: Icho considered this one the weakest in the pack, but I like it. I had no idea how to stop the platformer at the top, so I used a builders there and had to spare one later. So I backrouted this level.
A Humdrum Conundrum: This was a quick solve, but only since I knew this trick from a level in "Art Lems". (which wasn't required there, but I found it out by myself)
Oh, those talented Lemmings: Along with Panic room the best level in "Delta" for me. I love how everything falls into line here. and there is still variety. For example, Icho, Kaywhyn and I used the blocker at three different spots.
12 Steps to Success: Solving this was hard work! I'm not good with stackers, so maybe that's why its not among my favourites levels here, but I can definitely see why it is for others.
The Incredible Squashing Machine: Easy one which is nice from time to time. It's also a good one and I thin I found the intended solution here.
Make the most of your Lemmings: This was the easiest levels of the entire pack for me (including Alpha). Like others, I love 1-of-everything-levels and this one is no exception.
DEAR LITTLE BEASTIES: A lot of precision is required here. I exhausted everything to the max to save this dearly needed Extra-Lemming and it finally worked.
Curse of the Lemmings: This one was easier than I thought. I found a relatively clean solution, so I could spare some skills in the end.
Alpha:The Locked Room Mysteries: It was pretty clear what to do here. I must say I don't like this digger-trick that much, I think it's pretty repetitive. Easy level, though.
Unfriendly Neighbours: This really caused me some trouble. In lots of Zombie-based levels it's easy to find way to get rid of these beasties, but this was not the case here. So my solution is completely timing-based which makes this level - if it's intended - absolutely great!
These Lemmings and those Lemmings: I bombed through the block and used the lower part of the level in the end only. So I probably missed something - it felt like a backroute.
Crowd Control: I didnt' find this level easy at all and had a hard time to squeeze the Lemmings. Since it turned out to be impossible with the skills available, I played with the Release-rate a lot. But this was not necessary as I found out eventually.
Thick and thin: Phew, this was a mess. To be honest, I still don't know how to get all these Lemmings up to the exit. What saved me was the fact that I could lose some. The hardest level in the Alpha rank, at least for me.
A Sorting problem: My favourite level from the Alpha rank. I was clear from the beginning which exit the swimmers had to use, but I could isolate them in the beginning - everyhting else fell in line then.
The Big Dig: I feel that I backrouted this one since I just made it right on time and with a totally direct approach.
Equivalent Exchange: They first level I EVER played with laserers. I really wonder how Armani solved this with both sides not interacting with each other. It was a difficult one, especially with the "new" skill for me, but I found a quite elegant solution. I like this one!
Fun with Lasers: Compared with the level beforce, I made a big mess out of this. I don't know if my solution has something to do with what you had in your mind, but at least, it worked.
Escape from Zombie Island: A worthy conclusion of great pack. I was familiar with this basher-trick and used the digger-trick form Alpha 1 again, but at the wrong side of the level, at first.
