I think I was about 5 or 6 when I first saw it. I only remember vaguely, but I think I have the picture of "Just Dig" or some dirt style level in my head. I didn't want to play it though, I just wanted to watch someone else play.
When I had got a little older I browsed with a friend of mine though the various games, but we found Supaplex first and just played it not continuing searching.
I remember in elementary school we had an old comp. and played various games there too. I almost never played actively there though, but I remember us standing around the screen in a crowd watching; this were my only contacts to lemmings at that time.
After moving, I think in 2001, I began to play again, among other games also lemmings. I used to play a game for a few weeks or months, and after that I switched to another one. After some time, when I had played a couple of games, the cycle restarted and I continued games I played before. In 2003 I somehow found LemEdit and created a few levels, nothing special though. At the end of that year I found the Supaplex forum and stopped playing other games for over a year. In the beginning of 2005 I somehow got the feeling that I wanted to play lemmings again, and continued playing the original levels/ONML with WinLemm, later I registered here. I think the rest you may know. I still neither completed the original levels nor ONML, but at least for ONML I'm going to do it.
And yeah, I have to agree with DragonsLover, I somehow think that the older games are better. Why else should I still playing them while so many new ones exist?
Oh, and I just want to say again @JM, I didn't find those two feature, I just was the first one making a level supporting them. I got that information reading the conversation between ccexplore and Mindless in some thread, and after that I guessed that for the vgaspec file it might be the byte mentioned in rt's level format description.

IS01: Difficult -- Level 12: The Lemming Mental Institution

Save 95% of 100
Release rate: 20
Time: 7 minutes 22 seconds
Skills: 10 bombers, 50 builders, 10 bashers, 10 diggers

Good: The level really looks like a mental institution; the beginning of the music indicates some kind of madness; it's possible to save 100%.
Bad: Due to its size it requires a lot of straight building which can get boring after a while; the 100% route is easier than the one using bombers

Garjen01 - Level 8: The long way round
 
Save: 50/50
RR: 1
Time: 2 minutes
Skills: 3 builders, 5 miners

Good: Has a very nice-looking design; the 'long way round' route has a little puzzle element with only two kinds of skills and the time limit is fairly tight.
Bad: Worst thing is the backroute (?) not going the long way round; but also the (probably) intended route isn't too hard to find out, therefore it might have been placed a little earlier.

And yeah, I'd like Levipak3 to be reviewed next.

Well, mine look quite a bit different and more chaotic. It uses the same trick though.
I wonder whether the way I handled the right part is the intended one, I suppose yes.
Anyway, check the PM if you want to see my screenshot.

You seem to have triple posted, Geoo89! I deleted the other two since they were exactly the same as the first.

Sorry for that, thanks for deleting them. The forum was lagging; after some time still nothing had happened and I clicked again and later once more. (I gave it up then so I couldn't see the result.)

You have a second pack? When's it coming out?

As I said, you'll need to wait for some time for me to complete it. In fact, I don't know when I'll get ready with it; I won't make any predictions, maybe only a few weeks, maybe a couple of months...
I have ideas for almost all of the levels though, but created only a very few yet.

And somehow I doubt you'll be able to keep the pace over future levelpacks.

Careful now, or he might really set out to prove you wrong.

I'll try to, but Conway's doubt is certainly justified.
For at least pack two I think I'm able to keep the difficulty quite high since I have enough ideas for it: I have a list of 17 tricks/ideas I could use, although some of them seem to be almost as hard to implement into a level as ccexplore's shrugger trick.
In addition I have a little stack of small notes with a couple of ideas. The problem is that some of them were written down quite some ago and therefore maybe nothing special at all, also, for some of them I don't remember what I meant with it since most of my notes are imprecise, and a few of the ideas I already used.
But to be honest, I already considered this when I started editing. We'll see. And since my rate at making levels isn't high either I get time to think about new levels without lowering the rate too much at all.

But I don't know; maybe it's just your style. I think you certainly have the most talked about pack on this thread! It inspires me to want to return to my LemEditing days.

Nice to hear that. ...which reminds me, I should have some more tries at your levels, I have played only a few of them yet.
And yeah, I'd say it is my style. Tricky, small levels. As I do for Supaplex.

btw, I'd prefer Garjen03 or levipak3 to review.

I think it shouldn't be possible to solve it that way because (1) you cannot save the climber (2) cannot free both blockers without having at least one of them walking to the left. I'm quite sure that both reasons are correct.

Also, I'd call the glitch/trick for the level rather a trick; the effect is actually expectable.

Argh!

Level 8 is driving me insane! Whatever solution I build, there's always one problem that stops it from working!

Do you enjoy tormenting us Geoo89?

Well, I'm used to this especially playing Insane Steve's Hopeless levels.
I think you're on the wrong track with level 8: It is one of the levels using almost no precision or precise timing.

Also for level 10, conventional way to solve it shouldn't work. Remember, it's level 10.
