Hi bsmith,
Find my replays for your level pack attached. I've attached replays for both v1.43, as well as the FlexiTool NL version that namida made for your pack. I don't know how often you visit the forums these days, but my replays will be here. As someone who's only been posting here for 6 months, I eventually plan to post all my replays for the level packs I play in the appropriate level pack topic. Since these replays are for a pack for very Old Formats and Old Formats NL (actually, I don't know what version of NL the FlexiTool one is considered), they probably won't be of interest, especially if you're not updating this pack of yours anymore.
Remarks on the PackI actually played this pack several months ago earlier this year, but I unfortunately didn't have any replays saved due to not having the setting of autosave a replay if you're successful in solving the level. So, I revisited the pack and did just that to have replays yesterday. I started with the v1.43 one, and then afterwards I did the FlexiTool NL version, despite how the levels are exactly the same in both versions and that the latter is way more annoying to play due to only the minus key working for rewinding. I also commonly used the comma key for rewinding in NL, but apparently it doesn't work in the FlexiTool version

In any case, pretty much my solutions for the FlexiTool version are exactly the same as the v1.43 one, and it was a really quick solve anyway, as all the solutions I used were still fresh in my head. Also, I felt it really weird that the replays for for the FlexiTool version doesn't save replays in an Auto folder. Instead, it saves a replay along with an associated text file that lets you see things like which lemming you assigned a skill to, which I believe is what Lemmix does.
From the time I played this small pack earlier this year, I got to say these levels are absolutely no pushovers whatsoever, and the pack's overall difficulty is fairly high for a first pack by you. A lot of these were still great, enjoyable puzzles that I felt challenged me appropriately. Even the very first level of the pack in the Vanilla rank starts out with a difficult 2 of everything level, using only classic 8 skills. Vanilla 3 -
Compressed Sand is also somewhat difficult despite it being a remake of Easy When You Know How/Compression Method 1 from the original Lemmings, although it's certainly a nice solution that's much different. The remaining levels in the Vanilla rank were all small and very short, but they weren't difficult compared to the 2 levels I already mentioned, with the rank finisher being a remake of Nightmare on Lem Street/The Great Lemming Caper, as well as being a 2 of everything level. Still pretty easy, though. I pretty much enjoyed the entire Vanilla rank, though I say the only annoying one is Vanilla 5 -
Over the Top due to it being quite difficult to select the specific lemming you want when they're so close to each other since the lemming doesn't get highlighted in the very old NL version, this being the major drawback of using the old NL version. It can also somewhat be difficult, but with a limited skillset the solution should come pretty fast.
For the Chocolate rank, where only 1 NL skill is present in every level, it starts off with a remake of Patience/From the Boundary Line from the original Lemmings, Chocolate 1 -
Lateral Movement. This second rank level is somewhat easier than the previous first level of the first rank. Chocolate 4 -
Pole Jumpers, a remake of We Are Now at Lemcon 1/Poles Apart was probably the hardest one of the rank but nevertheless has a really nice solution that I like. Chocolate 2 -
Safe Descent was a really nice tricky puzzle. Chocolate 3 -
Not So Simple is aptly named, but only if you don't know how to turn a lemming around with the skills given. That's the only difficult thing in the level. Other than Chocolate 3 and 4, I thought the Chocolate rank was a bit easier than the Vanilla rank. Also, I kind of don't like my solution for Chocolate 6 -
Send Me a Postcard, clearly a reference to Postcard from Lemmingland from the original Lemmings, because of how I mined on a OWW. I don't even recall if this was the first solution I found months ago. I think in New Formats NL it's not possible to do what I just did when it comes to OWWs.
Finally, for the Neopolitan rank, it starts up with a difficult level, Neopolitan 1 -
Arctic Ascension (in the game, you have it as ascention, which is a misspelling). It takes some thought on how to get up on every landmass with the extremely restrictive skillset even though you have 4 of all the skills provided in the level. I also tend to have a difficult time with levels that have a lot of stackers, although this one isn't overly hard. Now that I've solved the level again months later, I think I do remember isolating another lemming the way I did in the replay. The hardest level of the rank is definitely Neopolitan 3 -
Dancing on a Highwire, as it's not easy to figure out how to get the crowd down at all. I guess this one could be considered a remake of Crazy 2 Dolly Dimple from ONML. The remaining levels of the rank are clearly remakes of levels from the original Lemmings. Neopolitan 2 -
One Minute Heroes is clearly based on Just a Minute from the Mayhem rank, Neoplitan 4 -
Take the Hard Way Down is a remake of Fun 30/Mayhem 24, Neoplitan 5 -
Top and Bottom is a remake of Fun 4/Mayhem 20, and finally Neoplitan 6 -
Off the Shelf Lemmings is a remake of Fun 3. The solutions to all of them were pretty nice, and none were too terribly difficult, although they aren't trivial either.
Overall, nice job with this pack. I really liked this pack, and I definitely felt challenged enough. Hope you're doing well, and hope to see you around here sometime
