Finally solved all the remaining contest levels. Here are all my replays for the NL entries (for the Lix replays, see the post right above this one), including all of my solutions to Icho's levels which I of course pre-tested, as well as my solutions for Crane's R3 and Niesch's R3, which I've also had the honor of pre-testing. I've attached 3 solutions for Niesch's R2, one of which is the talisman solution and the other two just slight variants of each other, as well as two solutions for Crane's R3, one of which is a solution from the pre-testing days, as well as the talisman solution.
Also I have the remaining videos up for the LDC levels

For part 1, see the above post.

https://youtu.be/4UG2jpppYc0For Armani's R2, I show Icho's intended solution after I show off my very hackish and extremely hard to pull off solution,
while for my R3 after I show my intended solutions I show off Icho's solution, as a way to thank him for all the super helpful feedback he has provided me to help me improve in my designs! 
I've already provided feedback on the R1's last time, so this will just be feedback for the R2's and R3's.
Rule 2 FeedbackLike R1, all these levels were a lot tougher than I thought! In particular, I found Armani's R2 to be the hardest of the entire pack, though that's because of the extremely hackish solution I found which is very different and much tougher than the intended solution that I personally would accept, but that's for Armani to decide. Sadly, I've solved all of these close to around the time the update phase is closed, so apologies to those people whose levels I backrouted and cannot release an update anymore for the LDC

My solution to The Tomato Watcher's R2 is most definitely a very glaring backroute, though that can easily be fixed with OWAs pointing to the right on the sand terrain

This took me a very long time to solve and hence was the hardest level for me in the entire contest. I initially tried some "Flow Control" by compressing the crowd so that they can both be released with stackers at the right time to get over the wall and also the second Milla statue, but unfortunately I wouldn't have enough stackers or I also have to place the first stack a few pixels away from the entrance so that I can bomb a faller to release the crowd but then the crowd wouldn't be bunched up properly for this. Then eventually I did away with that and tried going through the thin waterfall at the start with a well-placed basher and then bash again once on the other side after swimming through. However, this created a lot of problems as I was faced with being a skill short or the climbers would get themselves into trouble by going back out to the left.
After a long time, I discarded the above and went for a normal solution of simply bashing on through at the very start so that I could save the stackers for elsewhere. There are two very difficult to pull off parts here: After bombing the OWW, I bashed at such a time so that one another nearby Milla doesn't turn around and at a super precise location, platform so that the basher doesn't stop and continues on through to the pole. The other one is near the very end with the final wall, where the stack on top of the first one is bashed at such a time so that both sides of it are destroyed to allow the others through. I was fortunate in that there weren't any nearby Millas, giving the basher time to platform the final gap before anyone arrives and dies to the spikes.
So yea, very hard to pull off solution. I did consider the ceiling route, but this was another case of me coming to an incorrect conclusion of deciding it won't work before I even tried it myself
Somewhat tough, though the solution is obvious in terms of where the bombers need to go. The bigger problem is getting the execution right. I've attached two solutions, which are just slight variants of each other, as well as the talisman solution. This one was a bit fun to figure out after a time even though it can be a bit dizzying due to the splitters and figuring out how to prevent the splatting, as not a single one can splat.
Sorry TTW, I severely backrouted this one

As a result, some skills left and plenty of time to spare. Before I found this hackish solution, I initially used the glider to send one over the top, but by the time I mined the crowd out not enough time remains. Thus, I kept running out of time and as a result I got frustrated
Wow, I don't know why this level gave me so much trouble, but it's likely due to how I kept running into skill shortages or some Leminas will get into trouble before gaps were prepared. Good level, though I will have to agree with Icho here in that the time limit doesn't seem necessary in any way.
Rule 3 FeedbackThese levels didn't take anywhere near as long as the other two rulesets, but still some tough nuts here. Then again, I only had to play Armani's, TTW's, and Silken's R3's here, as I ended up pre-testing both Niesch's and Crane's R3's, and of course all of Icho's levels. As a result, only feedback to the first three I mentioned will be provided

Nice level. I actually had an attempt at this level while I was the courthouse for jury duty (it's a civic duty of USA people which is pretty dumb and is a huge waste of time and seems quite arbitrary as to who needs to come and attend) and nearly got the solution, but one of the basher locations was wrong. This level still took me the shortest amount of time to figure out out of all your contest levels though

Definitely not very hard but once again a level that ended with some frustration for me as I kept losing more lemmings than is allowed due to not finishing the final parts of the level on time before the crowd arrived. I'm sure it's simply the result of me making the level harder than it needed to be, though.
Harder than I thought, though too much jumping for my liking, so I'm in agreement with Icho that if the ruleset allowed less lemmings then it would had been better with less repetitive jumping. This one took a while to figure out how to get down safely since there are death drops pretty much everywhere. However, the rest of the level is easy once you figure out how to get to the floater pickups which allow you to get the bunch of pickups at the bottom on the left side more easily.
All rightie, thank goodness to finally have gotten through all levels here. I did get worry that I wouldn't be able to solve everything before the playing phase ended due to how late I came back to the game close to the deadline, but fortunately I was able to solve everything. Even if I didn't succeed here, I still be able to release videos of my solutions to them during the voting but off-site due to discussions of them not allowed unless they were already eliminated.
Thanks for the levels everyone and see you all for future LDCs!
