For what it's worth, attached are my complete thoughts on DoveLems.
Thanks so much for the kind words kaywhyn! Assuming I keep up my current rate of playing the game (which will almost certainly change once I have actual work to do again ) I can see myself having the occasional "banter" about various levels. And I could start level designing, I tend to think very visually, so I'm sure it's only a matter of time before ideas start to occur to me for my own levels - but before that happens I definitely look forward to exploring all the many (many) levels on offer here. It is slightly intimidating to see even the hardest DoveLems levels described as "Medium", but I suppose it didn't take me ALL that long to solve most of them...it certainly is a great pack for a smooth transition to the harder tricks that the original games didn't touch.
You're welcome. Thanks for sharing your thoughts on the level pack in the PDF file. I haven't read all your thoughts on every level of Dovelems, but there are a few points of interest in your intro paragraph. Some remarks:
Pimolems was the second custom pack I played after I finished Dovelems. So far, I have completed both of these on Lemmini. I have yet to take on the NL versions of them. Pimolems was a pack where I gave up in frustration and didn't come back to play the pack again for about 2-3 years. The level that stopped me dead in my tracks was Hurricane 3. When I did come back, I was able to get past it and proceed to finish the rest of the pack. It's definitely harder than Dovelems. As you have seen, Dovelems tends to have a very gentle difficulty curve and it stays fairly simple throughout, whereas for Pimolems, I say the difficulty really picks up about halfway through the second rank, but it definitely gets hard starting with the third rank and stays difficult all the way through the end of the Hurricane rank. Needless to say, Dovelems tends to stay closer and truer to the original Lemmings in terms of ranks and levels (30 levels in each of the 4 main ranks) and difficulty, whereas Pimolems is only slightly different in terms of structure (20 levels each in 7 ranks, except for the Special which has 5 levels in the NL version, two of which are Reunion levels, but only 3 in the Lemmini version) but is definitely more difficult.
Reunion was the third custom pack I played and is, to date, the largest custom pack I have completed (that will soon change because I am nearly done with Icho's other main pack, United). I too have only completed it on Lemmini. At the time when I played through the pack, I was working a job, which was why it took me 3 months to finish the pack. The level that had me stuck the longest was Nightmare 16. Regarding the pack, it has a really great difficulty curve, but it certainly gets harder much faster than the original game. In particular, the last few levels in the first rank are all difficult. However, I'm quite certain you'll be able to finish it. If you ever get terribly stuck, you can always ask for hints and send a replay for Icho to see, and he'll be glad to tell you whether or not if you're on the right track towards a solution.
Geoflems is a pack I certainly would like to play at some point. From what I read, it's on the much easier side, which I can certainly use after having played mostly United for the last several months, and the levels in there are quite brutal (hard-extreme). Though it's almost been a year since I first played the pack, and I have had so many struggles, I am getting very near the end (only 6 levels left in the Bonus rank, then just 4 Genocide levels I need to go back and resolve the new versions of and then I'll finally be done). Needless to say, after you finish Reunion and if you're definitely feeling up to it, feel free to take on Icho's other pack United, but be warned it's probably the most difficult pack there is currently available. It's definitely not for the faint of heart or the easily frustrated. Or feel free to stay to other easier packs. Up to you, of course.
