Added the LP link of Armani's Lemmings Uncharted to the OP, as I just recently completed the LP of the pack. Near the end, I saw that I was close to the 1 month mark since the time I started the LP (September 24, 2021), and so I made it my goal to finish the entire LP by yesterday, October 24, 2021. Luckily, I achieved this goal, so I'm satisfied for meeting a personal deadline I set for myself. The LP ended up being 66 videos long, almost as long as my LP of SEB Lems, at 75 (technically 76, since one of the recordings is missing but I didn't have OBS open

)
It was a very long and difficult struggle, especially once I got into the 3rd rank and beyond, but I managed to emerge from the other side in the end. This was a pack that I thought I was going to regret LPing, as I signed up for what sounded to be a very hard pack, possibly the new Lemmings United. So far, I'm in agreement that the pack isn't as hard as United, but it's pretty close. However, as I'm currently the only one to have solved every level at least once, the pack is still riddled with a lot of backroutes, so it's hard to say for certain how the difficulty compares to United. At the same time, I think I can say that the difficulty of the 5th and final rank, Aquarius, exceeds that of the Genocide rank of United. It's only because the entire rank was a very long and hard struggle for me despite all the backroutes I found for the rank. As a matter of fact, only two of my solutions were intended/acceptable, i.e, 18/20 were backroutes!

So, perhaps with the intended solutions properly enforced the pack may be as hard as United or just possibly exceed it by a bit.
In any case, I thought Armani did a great job for his first level pack. I immensely enjoyed it, and there are just a lot of remarkable gems in the pack that I consider my favorites. Thus, I can absolutely recommend the pack, but be warned that it's a really hard pack. Its difficulty definitely exceeds pretty much every level pack that I have solved, save for possibly United. Even then, as long as you don't let the difficulty get to you, you can make it to the end as well. I will look forward to any future levels/projects of Armani's.
At the same time, since I've solved every level at least once, I consider myself done with the pack and hence I can move on to other packs that I would like to get to. In particular, there's a few more that I would like to get to before the end of 2021. I think I have maybe 3 packs I would like to do before the year is over.
